12V MOSFET Drivers with Output Disable

for Multiple Phase Synchronous-Rectified Buck Converter

Features

General Description

The uP1951 is a quad, high voltage MOSFET driver All-In-One Synchronous Buck Drivers

optimized for driving four N-Channel MOSFETs in a dual

synchronous-rectified buck converter. Each driver is

capable of driving a 5000pF load with 30ns transition time.

This device combined with uPI multi-phase buck PWM

Bootstrapped High-Side Driver

Adaptive Anti-Shoot-Through Protection

Circuitry

controller forms a complete core voltage regulator for

advanced micro-processors.

Tri-State Input for Bridge Shutdown

Output Disable Control Turns Off both

The uP1951 features adaptive anti-shoot-through

protection that prevents cross-conduction of the external

MOSFET while maintaining minimum deadtime for

optimized efficiency.

MOSFETs

Under Voltage Lockout for Supply Input

WQFN3x3-16L Package

RoHS Compliant and Halogen Free

Both gate drives are turned off by pulling low OD# pin or

high-impedance at PWM pin, preventing rapid output

capacitor discharge during system shutdowns.

Applications

Core Voltage Supplies for Desktop, Motherboard

Other feature is supply input under voltage lockout. The

uP1951 is available in thermal enhanced WQFN3x3-16L

package.

CPUs

High Frequency Low Profile DC/DC Converters

High Current Low Voltage DC/DC Converters

Note: uPI products are compatible with the current IPC/

JEDEC J-STD-020 requirement. They are halogen-free,

RoHS compliant and 100% matte tin (Sn) plating that are

suitable for use in SnPb or Pb-free soldering processes.
