UP6281 PDF Datasheet – 12V MOSFET Driver

Posted on by pinout

A MOSFET driver is a specialized integrated circuit (IC) designed to provide the necessary electrical signals to drive metal-oxide-semiconductor field-effect transistors (MOSFETs) efficiently and effectively. MOSFETs are commonly used as electronic switches in a wide range of applications, including power electronics, motor control, voltage regulation, and more. A MOSFET driver ensures that the MOSFET is turned on and off rapidly and reliably, optimizing its performance and minimizing switching losses.

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 […]

Description

This is Off-Line PWM Controllers with Integrated Power MOSFET.

An off-line PWM controller, also known as a flyback controller, is an integrated circuit (IC) designed to control the operation of an off-line switching power supply. Off-line power supplies are used to convert AC voltage from the mains power source into regulated DC voltage for various applications, such as in consumer electronics, LED lighting, and industrial equipment.

The STR-W6000S series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC. The low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions. The product achieves high cost-performance power supply systems with few external components.
