IRF3546

  60A Dual Integrated Power Block  IRF3546 FEATURES Peak efficiency up to 94% at 1.2V Two pairs of control and synchronous MOSFETs in a single PQFN package Proprietary package minimizes package parasitic and simplifies PCB layout Input voltage (VIN) range of 4.5V to 21V Output current capability of 30A/phase Ultra-low Rg MOSFET technology minimizes switching losses for optimized high frequency performance Synchronous MOSFET with monolithic integrated Schottky diode reduces dead-time and diode reverse recovery losses Efficient dual side cooling Small 6mm x 8 mm x 0.9mm PQFN package Lead-free RoHS compliant package  The IRF3546 dual integrated Power Block copackages two pairs of high performance control and synchronous MOSFETs and is ideal for use in highdensity two-phase synchronous buck converters. It is optimized internally for PCB layout, heat transfer and package inductance. Coupled with the latest generation of IR MOSFET technology, the IRF3546 provides higher efficiency at low output voltages required by cutting edge CPU, GPU and DDR memory designs. High switching frequency enables high performance transient response, allowing miniaturization of output inductors, as well as input and output capacitors while maintaining industry leading efficiency. Integrating two phases in one package while still providing superior efficiency and thermal performance, the IRF3546 enables smallest size solutions. The IRF3546 uses IR’s latest generation of low voltag...
