3 Description

The LP8762-Q1 device is designed to meet the power

management requirements of the latest processors

and platforms in various safety-relevant automotive

and industrial applications. The device has four stepdown

DC/DC converter cores, that are configurable

for five different phase configurations from one 4-

phase output to four 1-phase outputs. The device

settings can be changed by I2C-compatible serial

interface or by a SPI serial interface.

The automatic PFM/PWM (AUTO mode) operation

together with the automatic phase adding and phase

shedding maximizes efficiency over a wide outputcurrent

range. The LP8762-Q1 device supports

remote differential voltage sensing for multiphase

outputs to compensate IR drop between the regulator

output and the point-of-load (POL) that improves the

accuracy of the output voltage. The switching clock

can be forced to PWM mode and the phases are

interleaved. The switching can be synchronized to

an external clock and spread-spectrum mode can be

enabled to minimize the disturbances.
