Overview
uP6281 12V MOSFET Drivers with Output Disable for Single Phase Synchronous-Rectified Buck Converter General Description The uP6281 is a dual, high voltage MOSFET driver optimized for driving two N-Channel MOSFETs in a synchronousrectified buck converter.
Each driver is capable of driving a 5000pF load with 30ns transition time.
This device combined with uPI multi-phase buck PWM controller forms a complete core voltage regulator for advanced micro-processors.
The uP6281 features adaptive anti-shoot-through protection that prevents cross-conduction of the external MOSFET while maintains minimum deadtime for optimized efficiency.
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.
Other feature is supply input under voltage lockout.
The uP6281 is available in thermal enhanced PSOP-8L or WDFN3x3-8L packages.
