3 Description

The LP87702-Q1 helps meet the power management

requirements of the latest platforms, particularly in

automotive radar and camera and industrial radar

applications. The device contains two step-down

DC/DC converters, and a 5-V boost converter

to support safety critical applications. The device

integrates two voltage monitoring inputs for external

power supplies and a window watchdog.

The automatic PWM/PFM (AUTO mode) operation

gives high efficiency over a wide output current range

for buck converters. The LP87702-Q1 uses remote

voltage sensing to compensate IR drop between the

converter output and the point-of-load, thus improving

the accuracy of the output voltage.
