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.
