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/bypass
switch. 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. During start-up and voltage change, the
device controls the output slew rate for minimum output voltage overshoot and inrush current. This
device contains one-time-programmable (OTP) memory. Each orderable part number has specific OTP
settings for a given application. Details of the default OTP configuration for each orderable part
number can be found in the technical reference manual.
