3 Description

The CSD95373AQ5M NexFET™ Power Stage is a

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

density Synchronous Buck converters. This product

integrates the driver IC and NexFET technology to

complete the power stage switching function. The driver IC has a built-in selectable diode emulation

function that enables DCM operation to improve light

load efficiency. This combination produces high

current, high efficiency, and high speed switching

capability in a small 5 × 6 mm outline package. It also

integrates the temperature sensing functionality to

simplify system design and improve accuracy. In

addition, the PCB footprint has been optimized to

help reduce design time and simplify the completion

of the overall system design.
