 NCP9002 1.3 Watt Audio Power Amplifier with Fast Turn On Time
The NCP9002 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The NCP9002 is capable of delivering 1.3 W of continuous average power to an 8.0 W BTL load from a 5.0 V power supply, and 1.0 W to a 4.0 W BTL load from a 3.6 V power supply. The NCP9002 provides high quality audio while requiring few external components and minimal power consumption. It features a low-power consumption shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low. The NCP9002 contains circuitry to prevent from "pop and click" noise that would otherwise occur during turn-on and turn-off transitions. For maximum flexibility, the NCP9002 provides an externally controlled gain (with resistors), as well as an externally controlled turn-on time (with the bypass capacitor). When using a 1 mF bypass capacitor, it offers 100 ms wake up time. Due to its excellent PSRR, it can be directly connected to the battery, saving the use of an LDO. This device is available in a 9-Pin Flip-Chip CSP (Lead-Free).

Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. Maximum electrical ratings are defined as those values beyond which damage to the device may occur at TA = +25C. 2. The thermal shutdown set to 160C (typical) avoids irreversible damage on the device due to power dissipation. For further information see page 9. 3.

NCP9002
APPLICATION INFORMATION
Detailed Description
The NCP9002 audio amplifier can operate under 2.6 V until 5.5 V power supply. With less than 1% THD+N, B version can deliver up to 1.2 W rms output power to an 8.0 W load (Vp = 5.0 V). If application allows to reach 10% THD+N, then 1.6 W can be provided using a 5.0 V power supply. The structure of the NCP9002 is basically composed of two identical internal power amplifiers; the first one is externally configurable with gain-setting resistors Rin and Rf (the closed-loop gain is fixed by the ratios of these resistors) and the second is internally fixed in an inverting unity-gain configuration by two resistors of 20 kW. So the load is driven differentially through OUTA and OUTB outputs. This configuration eliminates the need for an output coupling capacitor. The NCP9002 has around 10 kW output impedance in the shutdown mode.
Internal Power Amplifier
is no audible pop click noise, especially when the input cut off frequency is higher than 100 Hz.
Shutdown Function
The device enters shutdown mode when shutdown signal is low. During the shutdown mode, the DC quiescent current of the circuit does not exceed 100 nA. In this configuration, the output impedance is 10 kW on each output.
Current Limit Circuit
The output PMOS and NMOS transistors of the amplifier were designed to deliver the output power of the specifications without clipping. The channel resistance (Ron) of the NMOS and PMOS transistors does not exceed 0.6 W when they drive current. The structure of the internal power amplifier is composed of three symmetrical gain stages, first and medium gain stages are transconductance gain stages to obtain maximum bandwidth and DC gain.
Turn-On and Turn-Off Transitions
The maximum output power of the circuit (Porms = 1.0 W, Vp = 5.0 V, RL = 8.0 W) requires a peak current in the load of 500 mA. In order to limit the excessive power dissipation in the load when a short-circuit occurs, the current limit in the load is fixed to 800 mA. The current in the four output MOS transistors are real-time controlled, and when one current exceeds 800 mA, the gate voltage of the MOS transistor is clipped and no more current can be delivered.
Thermal Overload Protection
A cycle with a turn-on and turn-off transition is illustrated with plots that show both single ended signals on the previous page. In order to eliminate "pop and click" noises during transitions, output power in the load must be slowly established or cut. When logic high is applied to the shutdown pin, the bypass voltage begins to rise exponentially and once the output DC level is around the common mode voltage, the gain is established instantaneously. This way to turn-on the device is optimized in terms of rejection of "pop and click" noises. The device has the same behavior when it is turned-off by a logic low on the shutdown pin. During the shutdown mode, amplifier outputs are connected to the ground. When a shutdown low level is applied, with 1 mF bypass capacitor, it takes 65 ms before the DC output level is tied to Ground on each output. However, no audio signal will be provided to the BTL load only 1 ms after the falling edge on the shutdown pin. With 1 mF bypass capacitor, turn on time is set to 90 ms. This fast turn on time added to a very low shutdown current saves battery life and brings flexibility when designing the audio section of the final application. NCP9002 is a zero pop noise device when using a differential audio input. In case of a single ended one, there
Internal amplifiers are switched off when the temperature exceeds 160C, and will be switched on again only when the temperature decreases fewer than 140C. The NCP9002 is unity-gain stable and requires no external components besides gain-setting resistors, an input coupling capacitor and a proper bypassing capacitor in the typical application. The first amplifier is externally configurable (Rf and Rin), while the second is fixed in an inverting unity gain configuration. The differential-ended amplifier presents two major advantages: - The possible output power is four times larger (the output swing is doubled) as compared to a single-ended amplifier under the same conditions. - Output pins (OUTA and OUTB) are biased at the same potential Vp/2, this eliminates the need for an output coupling capacitor required with a single-ended amplifier configuration. The differential closed loop-gain of the amplifier is given by Avd + 2 * f + orms . Rin Vinrms Output power delivered to the load is given by
Porms + (Vopeak)2 (Vopeak is the peak differential 2 * RL R V
output voltage). When choosing gain configuration to obtain the desired output power, check that the amplifier is not current limited or clipped. The maximum current which can be delivered to the load is 500 mA Iopeak +

NCP9002
Gain-Setting Resistor Selection (Rin and Rf)
Rin and Rf set the closed-loop gain of the amplifier. In order to optimize device and system performance, the NCP9002 should be used in low gain configurations. The low gain configuration minimizes THD + noise values and maximizes the signal to noise ratio, and the amplifier can still be used without running into the bandwidth limitations. A closed loop gain in the range from 2 to 5 is recommended to optimize overall system performance. An input resistor (Rin) value of 22 kW is realistic in most of applications, and doesn't require the use of a too large capacitor Cin.
Input Capacitor Selection (Cin)
large input coupling capacitor requires more time to reach its quiescent DC voltage (Vp/2) and can increase the turn-on pops when a single ended audio input is used. An input capacitor value between 33 nF and 220 nF performs well in many applications (With Rin = 22 KW).
Bypass Capacitor Selection (Cby)
The input coupling capacitor blocks the DC voltage at the amplifier input terminal. This capacitor creates a high-pass filter with Rin, the cut-off frequency is given by
fc + 1 . 2 * P * Rin * Cin
The bypass capacitor Cby provides half-supply filtering and determines how fast the NCP9002 turns on (see Figure 21). With a differential audio input, the amplifier will be a zero pop noise device no matter the bypass capacitor. With a single ended audio input, this capacitor is a critical component to minimize the turn-on pop. A 1.0 mF bypass capacitor value (Cin = < 0.39 mF) should produce clickless and popless shutdown transitions. The amplifier is still functional with a 0.1 mF capacitor value but is more susceptible to "pop and click" noises. Thus, a 1.0 mF bypassing capacitor is recommended.
The size of the capacitor must be large enough to couple in low frequencies without severe attenuation. However a
