uPI Semiconductor
12V MOSFET Driver
Package Type: PSOP-8
The UP1952 is a dual, high voltage MOSFET driver optimized for driving two N-Channel MOSFETs in a synchronous-rectified 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 UP1952 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 UP1952 is available in thermal enhanced PSOP-8L and WDFN3x3-8L packages.
