Description

The PT4820 Excalibur™ power modules are a series of isolated tripleoutput DC/DC converters that operate from a standard (48V) central office supply. Rated for up to 35W, these regulators are ideal for powering many mixed logic applications.

The triple-output voltage combination allows for a compact multiple-output power supply in a single low-profile DC/DC module.

The available output voltage options include a low-voltage power bus for a DSP or ASIC core, and two additional standard logic supply voltages.

The PT4820 series incorporates many features to simplify system integration. These include a flexible On/Off enable control, an input under-voltage lock-out, and overtemperature protection. All outputs have short-circuit protection and are internally sequenced to meet the power-up and power-down requirements of popular DSP ICs.

The PT4820 series is housed in a space-saving solderable case. The module requires no external heat sink and can occupy as little as 1.3 in2 of PCB area.
