PFC & PWM Control IC
ADE-204-072 (Z) Rev.0 Aug. 2002 Description
The HA16158 is a power supply controller IC combining an AC-DC converter switching controller for power factor correction and an off-line power supply switching controller. The PFC (power factor correction) section employs average current mode PWM and the off-line power supply control section employs peak current mode PWM. The HA16158 allows the operating frequency to be varied with a single timing resistance, enabling it to be used for a variety of applications. The PFC operation can be turned on and off by an external control signal. Use of this on/off function makes it possible to disable PFC operation at a low line voltage, or to perform remote control operation from the transformer secondary side. The PWM controller includes a power-saving function that reduces the operating frequency to a maximum of 1/64 in the standby state, greatly decreasing switching loss. The PFC section and PWM section are each provided with a soft start control pin, enabling a soft start time to be set easily.

Functional Description
1. UVL Circuit The UVL circuit monitors the Vcc voltage and halts operation of the IC in the event of a low voltage. The voltage for detecting Vcc has a hysteresis characteristic, with 16.0 V as the start threshold and 10.0 V as the shutdown threshold. When the IC has been halted by the UVL circuit, control is performed to fix driver circuit output low and halt VREF output and the oscillator.

2. Soft Start Circuit (for PWM Control) This function gradually increases the pulse width of the PWM-OUT pin from a 0% duty cycle at start-up to prevent a sudden increase in the pulse width that may cause problems such as transient stress on external parts or overshoot of the secondary-side output voltage. The soft start time can easily be set with a single external capacitance.

Figure 2 Soft start time tss-pwm is determined by PWM-SS pin connection capacitance Css-pwm and an internal constant, and can be estimated using the equation shown below. Soft start time tss-pwm is the time until the PWM-SS pin voltage reaches upper-end voltage 3.2 V of the IC-internal CT voltage waveform after VREF starts up following UVLO release. Soft start time tss-pwm when Css-pwm is 3.3 nF is given by the following equation.
tss-pwm = 33 [nF] x 3.2 [V] Css-pwm x Vct-H = 25 [A] Iss-pwm

Figure 3 Soft start time tss-pfc is determined by PFC-SS pin connection capacitance Css-pfc and an internal constant, and can be estimated using the equation shown below. Soft start time tss-pfc is the time until the PFC-SS pin voltage reaches lower-end voltage 0.65 V of the ICinternal RAMP voltage waveform after VREF starts up following UVLO release. Soft start time tss-pfc when Css-pfc is 3.3 nF is given by the following equation.
tss-pfc = 33 [nF] x (5 - 0.65) Css-pfc x (VREF - Vramp-L) = 25 [A] Iss-pwm

4. PFC On/Off Function On/off control of the PFC function can be performed using the PFC-ON pin. If an AC voltage that has undergone primary rectification and has been divided by an external resistance is input, it is possible to halt PFC operation in the event of a low input voltage. On/off control is also possible by using a logic signal. This IC also incorporates a function that automatically detects a 100 V system or 200 V system AC voltage at the PFC-ON pin, and switches multiplier gain and the PFC-CS comparison voltage. These functions simplify the design of a power supply compatible with worldwide input.

5. Power Saving in Standby State (for PWM Control) When the output load is light, as in the standby state, the operating frequency of the PWM control section is automatically decreased in order to reduce switching loss. Standby detection is performed by monitoring the PWM-COMP voltage, and the operating frequency is decreased to a maximum of 1/64 of the reference frequency determined by an external timing resistance. As standby detection is performed on a reference frequency pulse-by-pulse basis, the frequency varies gently according to the output load.

6. Overvoltage Latch Protection (for PWM Control) This is a protection function that halts PWM-OUT and PFC-OUT if the secondary-side PWM output voltage is abnormally high. Overvoltage signal input is shared with the PWM-SS pin. When this pin is pulled up to 4.0 V or higher, the control circuit identifies an overvoltage error and halts PWM-OUT and PFC-OUT. The power supply is turned off, and the latch is released when the VCC voltage falls to 7.1 V or below.

7. Operating Frequency The operating frequency is adjusted by timing resinstance RT. Adjustment examples are shown in the graph below. The operating frequency fpwm in the PWM section is determined by the RT. The operating frequency fpfc in the PFC section is half the value of fpwm. The operating frequency in the PWM section can be estimated using the approximate equation shown below. RT = 200 k:
fpwm fpfc = 2.60 x 1010 = 130 [kHz] RT
fpwm = 65 [kHz] 2
This is only an approximate equation, and the higher the frequency, the greater will be the degree of error of the approximate equation due to the effects of the delay time in the internal circuit, etc. When the operating frequency is adjusted, it is essential to confirm operation using the actual system.
