UP6281 - 12V MOSFET Drivers

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.

Key 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. † Bootstrapped High-Side Driver † Adaptive Anti-Shoot-Through Pro.

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.
