3 Description

The LP8756x-Q1 device is designed to meet the

power-management requirements of the latest

processors and platforms in various automotive

power applications. The device contains four stepdown

DC/DC converter cores, which are configured

as a 4-phase output, 3-phase and 1-phase outputs,

2-phase and 2-phase outputs, one 2-phase and two

1-phase outputs, or four 1-phase outputs. The device

is controlled by an I2C-compatible serial interface and

by enable signals.

The automatic pulse-width-modulation (PWM) to

pulsed-frequency-modulation (PFM) operation (AUTO

mode), together with the automatic phase adding and

phase shedding, maximizes efficiency over a wide

output-current range. The LP8756x-Q1 supports

remote differential-voltage sensing for multiphase

outputs to compensate IR drop between the regulator

output and the point-of-load (POL) improving the

accuracy of the output voltage. The switching clock

can be forced to PWM mode and also synchronized

to an external clock to minimize the disturbances.

The LP8756x-Q1 device supports load-current

measurement without the addition of external currentsense

resistors. The device also supports

programmable start-up and shutdown delays and

sequences synchronized to enable signals. The

sequences can include GPIO signals to control

external regulators, load switches, and processor

reset. During start-up and voltage change, the device

controls the output slew rate to minimize outputvoltage

overshoot and in-rush current.
