Applications
* Networking Gear * Data Communications * Telecommunications * Industrial / Medical
The W30 Family of high efficiency DC/DC converters offer power levels of up to 30 Watts, exceeding that of other products with the same Industry-Standard Pinouts, while providing much smaller footprints. With a wide input voltage range and single outputs, ranging from 1.5 to 15 Volts, these converters provide versatility without sacrificing the board space. All models feature an input filter and microcontroller-based protection features. The open frame construction allows very efficient heat transfer with no hot spots. All converters combine creative design practices with highly derated power devices to achieve superior efficiencies (up to 94%), reliability, high performance and low cost solution to systems designers. * No minimum load required * On/Off pin control * -40C to +85C ambient operation * Output adjustment +/-10% range * 1500V, 10M input-to-output isolation * Output overcurrent protection * Input Under voltage protection * Input Over voltage protection * Synchronous rectification topology * MTBF of up to 1,000,000 hours @ 50C (Bellcore) * Over Voltage protection * Over Temperature protection * Please add suffix "A" or "B", depending on Pinout * Please add suffix "N" for Negative Logic * Delivers up to 30W in 1" x 2" package with Industry-Standard Pinouts * UL 60950 pending, TUV EN60950 and CSA C22.2 No. (Pending)

Basic Operations and Functions W30 Family is a high efficiency, isolated DC/DC converter. Neither heat sink nor airflow is required when the unit operates at ambient temperature of 25C. The unit has basic control, output adjustment and protection functions. Input (Pin 2, Pin 3) Input power Vin(+) must be connected to Positive input pin 3; Input power Vin(-) must be connected to Negative input pin2. Output (Pin 4, Pin 5) Output power Vout(+) must be connected to Positive output pin 4; Output power Vout(-) must be connected to Negative output pin6. ON/OFF (Pin 1) Permits the user to maintain unit On/Off, in order to properly sequence different power supplies and reduce power consumption during the standby condition. There are two ON/OFF control options: positive logic (W30-SX) and negative logic (W30-SXN). Both are referenced to Vin-. Pin 1 is the "Enable" pin, connecting a TTL compatible pin. A TTL control signal to this pin, according to the specification, turns the unit on or off. The positive logic unit turns on when the pin is at logic high or open, and turns off at logic low. The negative logic unit turns on when the pin is at logic low, and turns off at logic high state. Typical ON/OFF connection is shown in Fig 1.
FOR POTTED UNITS AND OTHER AVAILABLE VOLTAGES AND FEATURES PLEASE CONSULT THE FACTORY
Remote Sense The unit does NOT have remote sense pins. Output Trim (Pin 6) Permits the user to adjust the output voltage up or down to achieve the custom voltage or to make the output voltage margining.

ON/OFF
The unit's output voltage can be adjusted up 10% or down 10% relative to the rated output voltage by adding an external resistor between pin 6 and one of the output pins (pin 4 and 5). To increase the output voltage, a trim resistor should be connected between pin 6(Trim) and pin 5 (Vout-). To decrease the output voltage, a trim resistor should be connected between pin 6 (Trim) and pin 4 (Vout+).
