Description:

The CSD95492QVM NexFET™ power stage is a highly optimized design for high-power, high-power-density synchronous step-down converters. This product integrates the driver IC and power MOSFETs to complete the power-stage switching function. This combination provides high current, high efficiency and high-speed switching in a 4mm × 5mm form-factor package. It also integrates accurate current sensing and temperature sensing to simplify system design and improve accuracy. In addition, the PCB footprint has been optimized to help reduce design time and simplify overall system design.
