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.
