PT3322

The PT3320 is a series of high-input voltage, 30 Watt DC to DC converters, housed in a vertical or horizontal 19-pin SIP package. These regulators are fully isolated for operation from a 36 to 75V input voltage source, making them suitable for telecom and other applications that utilize a 48V distributed power bus.

The PT3320 series is available with output voltages from 1.8V to 15V. The output voltage is adjustable from 90 to 110% of nominal with the addition of an external resistor. Features include an inhibit function and a differential remote sense to compensate for voltage drop between the regulator and load. The PT3320 includes built in current limit, short circuit protection, and overtemperature shutdown. The PT3320 requires a 330F output capacitor for proper operation.
