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.
