RT9628A
High
Voltage Synchronous Rectified Triple Channel Buck
MOSFET Driver for Notebook Computer
General Description
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.
The drivers are capable of driving a 3nF load with fast rising/falling time and fast propagation delay.
