uP1965S

5V MOSFET Driver with Output Disable for Single Phase

Synchronous-Rectified Buck Converter

Features

General Description

Single 5V Driving Voltage Output

Integrated Bootstrap Diode

The uP1965S is 5V MOSFET driver optimized for driving

twoN-channel MOSFETs in a synchronous rectified buck

converter for mobile computing application. This part has

integrated bootstrap diode to eliminate external component

count. The resistor commonly placed between MOSFET

gate and source for discharge is also integrated, making

external component minimal. This device combined with

uPI multi-phase buck PWM controller forms a complete

core voltage regulator for advanced microprocessors.

Integrated Gate-to-Source Discharge Resistors

Enable/Disable Control

Allow PWM Pin as Multi-Function Setting

Application

Three PWM Input States: High, Low and Tri-State

Tri-State Input for Bridge Shutdown

Anti-Shoot-Through Protection Circuitry

Under Voltage Lockout for Supply Input

WDFN2x2-8L Package

The uP1965S supports enable/disable function that reduces

the power consumption to prolong battery life. Both gate

drives are turned off by pulling low ENpin or high-impedance

at PWM pin, preventing rapid output capacitor discharge

during system shutdown. This device also supports three

PWM input states that along with PWM controller to provide

a complete power solution.

RoHS Compliant and Halogen Free

Applications

Desktop/Laptop CPU/GPU Core Voltage

The uP1965S implements anti-shoot-through protection

that prevents cross-conduction of the external MOSFET

while maintains minimum deadtime for optimized efficiency.

This device also supports supply input under voltage

lockout. The uP1965S is available in thermally enhanced

WDFN2x2-8L package.

Note:

(1) Please check the sample/production availability with

uPI representatives.

(2) uPI products are compatible with the current IPC/

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

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

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