MP2910 - Data Sheet

The MP2910 is a dual output with one
synchronous buck PWM and one linear
controller. The part is used to generate logicsupply voltages for PC based systems. MP2910
includes internal soft-start, frequencycompensation networks, power good signaling
with specific sequence, and it comes all of the
logic control, output adjustment, power
monitoring and protection functions into a small
footprint package. The part is operated at fixed
300 kHz frequency providing an optimum
compromise between efficiency, external
component size, and cost. The linear controller
is implemented to drive an external MOSFET
for regulation and it's adjustable by setting
external resistors. Moreover the specific internal
PG sequence and indicator is also implemented
to conform to Intel® new platform requirement
on FSB_VTT power plane. An adjustable overcurrent protection (OCP) is proposed to monitor
the voltage drop across the RDS(ON) of the lower
MOSFET for synchronous buck PWM DC-DC
controller.
