3 Description

The CSD95377Q4M NexFET™ power stage is a

highly-optimized design for use in a high power, high

density synchronous buck converter. This product

integrates the driver IC and power MOSFETs to

complete the power stage switching function. The

driver IC has built-in selectable diode emulation

function enables Discontinuous Conduction Mode

(DCM) operation to improve light load efficiency. This

combination produces high-current, high-efficiency,

and high-speed switching capability in a small 3.5

mm × 4.5 mm outline package. In addition, the PCB

footprint has been optimized to help reduce design

time and simplify the completion of the overall system

design.
