PT7745A

20 -A可编程集成开关稳压器 20-A Programmable Integrated Switching Regulator

Description

The PT7711 Excalibur™ power module is a 20-A integrated switching regulator ISR housed a 27-pin space-saving copper package. Operating from a +5V input bus, the PT7711 produces a tightly regulated output voltage that is programmable over the range, 1.3V to 3.5V. The output voltage is selected via 5-bit input code, which is compatible with the VRM specifications defined by Intel®.

This regulator is most suitable for microprocessor and DSP applications requiring core or I/O logic supply voltages as low as 1.3V.

The PT7711 regulator incorporates output short-circuit protection, and a differential remote sense to compensate for voltage drop between the regulator and load.
