RT9628A

High Voltage Synchronous Rectified Triple Channel Buck

MOSFET Driver for Notebook Computer

General Description

Features

^Triple Channel Driver

The RT9628A is a high frequency, triple Channel driver

specifically designed to drive two power N-MOSFETs in

each channel of a synchronous-rectified Buck converter

topology. It is especially suited for mobile computing

applications that require high efficiency and excellent

thermal performance. This driver, combined with Richtek's

series of multi-phase Buck PWM controllers, provides a

complete core voltage regulator solution for advanced

microprocessors.

^Each Channel Drives Two N-MOSFETs

^Adaptive Shoot-Through Protection

^0.5Ω On-Resistance, 4A Sink Current Capability

^Supports High Switching Frequency

^Tri-State PWM Input for Power Stage Shutdown

^Output Disable Function

^Integrated Boost Switch

^Low Bias Supply Current

^VCC POR Feature Integrated

The drivers are capable of driving a 3nF load with fast

rising/falling time and fast propagation delay. This device

implements bootstrapping on the upper gates with only a

single external capacitor. This reduces implementation

complexity and allows the use of higher performance, cost

effective,N-MOSFETs.Adaptive shoot through protection

is integrated to prevent both MOSFETs from conducting

simultaneously.

Applications

 Core Voltage Supplies for Intel^®/ AMD^®Mobile

Microprocessors

 High Frequency Low ProfileDC/DC Converters

 High Current Low Output VoltageDC/DC Converters

 High Input VoltageDC/DC Converters
