Description
The PT3320 series is a single-output isolated DC/DC converter, housed in a 19-pin aluminum SIP package. These modules are UL, CSA, and VDE approved for telecom applications, and rated at 30 watts or 8 A. Standard output voltages range from 1.8 V to 15 V, each adjustable by up to ±10% of nominal. Operating features include a remote on/off control, an under-voltage-lockout (UVLO), and a differential remote sense. The PT3320 series also incorporates many protection features. These include output current limit, short-circuit prot e c t i o n , and over-temperature shutdown. A 330µF of output capacitance is required for proper operation.

Notes: (1) The DC/DC converter will operate at no load with reduced specifications. (2) T h e Remote On/Off input has an internal pull-up. If it is left open circuit the module will operate when input power is applied. A low-leakage (<100nA) MOSFET is recommended to control this input. The open-circuit voltage is less than 10V. See application notes for interface considerations. (3) Output capacitor values are absolute. Allowances must be made for any additional de-coupling capacitors and the total external capacitor tolerance. The value of external capacitance is limited due to regulator startup current requirements. Consult the factory for further details. (4) For operation below 0°C, the required external output capacitor must have temperature stable characteristics. E.g. Tantalum or Oscon® types. (5) See Safe Operating Area curves or contact the factory for the appropriate thermal derating.
