3 Description
The LP8752x-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 LP8752x-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 LP8752x-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.
