MP2910

Synchronous Buck PWM DC-DC

and Linear Power Controller

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2910 is a dual output with one

synchronous buck PWM and one linear

controller. The part is used to generate logic-

supply voltages for PC based systems. MP2910



Operating with 5V or 12V Supply Voltage

Drives ALL Low Cost N-Channel MOSFETs

Voltage Mode PWM Control

300kHz Fixed Frequency Oscillator

Fast Transient Response:

High speed GM Amplifier

Full 0 to 100% Duty Ratio

Internal Soft-Start

Adaptive Non-Overlapping Gate Driver

Over-Current Fault Monitor on MOSFET, No

Current Sense Resistor Required

Specific Power Good Indicator for Intel®

Grantsdale FSB_VTT Power Sequence

Available in a SOIC-14 Package and a

SOIC8E Package.

includes

internal

soft-start,

frequency-

compensation 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 over-

current protection (OCP) is proposed to monitor

the voltage drop across the R_DS(ON)of the lower

MOSFET for synchronous buck PWM DC-DC

controller.
