Description
General part information
LP87702-Q1 Series
The LP87702-Q1helps 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.
Programmable start-up and shutdown sequences synchronized to the enable signal are supported, including general purpose digital outputs.
