Products Detail

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 protection, and over-temperature shutdown. A 330µF of output capacitance is required for proper operation.
