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 […]

Features :

1. All-In-One Synchronous Buck Drivers

2. Bootstrapped High-Side Driver

3. Adaptive Anti-Shoot-Through Protection Circuitry

4. 1 PWM Signal Generates both Drivers

5. Tri-State Input for Bridge Shutdown

6. Output Disable Control Turns Off both MOSFETs

7. Under Voltage Lockout for Supply Input
