FDMF6730

Driver plus FET Multi-chip Module

Features

General Description

Over 95% efficiency

The FDMF6730 is a high efficiency Driver plus MOSFET power

stage solution optimized for Ultra Mobile PC (UMPC) system

power voltage supplies. It is fully compliant with the Intel Ultra-

Mobile Driver MOS (uDrMOS) Specification. The MOSFETs and

driver have been optimized to perform with high efficiency at

light and medium loads, ideal for compact PC devices.

Internal 5V regulator for gate drive

6V-16V input range

1MHz max operating frequency

SMOD operation capability for light load efficiency

5A current capability (10A with PASS FET)

The internal driver IC integrates two highly efficient LDOs for

internal gate-drive and external circuitry. The bootstrap diode is

also integrated within the IC. When operating with a single low

side MOSFET the uDrMOS module is capable of delivering up

to 5A of continuous current. The PASS transistor may be easily

routed in parallel with the low side MOSFET to provide up to

10A. The module also incorporates an over current protection

Current limit set by R

sensing to minimize power losses
