12V MOSFET Drivers with Output Disable

for Single Phase Synchronous-Rectified Buck Converter

Features

General Description

The uP1952 is a dual, high voltage MOSFET driver All-In-One Synchronous Buck Drivers

optimized for driving two N-Channel MOSFETs in a

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 uP1952 features adaptive anti-shoot-through protection

that prevents cross-conduction of the external MOSFET

while maintains minimum deadtime for optimized efficiency.

MOSFETs

Under Voltage Lockout for Supply Input

PSOP - 8L Package

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.

RoHS Compliant and Halogen Free

Applications

Core Voltage Supplies for Desktop, Motherboard

Other feature is supply input under voltage lockout. The

uP1952 is available in thermal enhanced PSOP-8L

package.
