DESCRIPTION
The CSD97370Q5M NexFET Power Stage is an optimized design for use in a high power, high density
Synchronous Buck converter. This product integrates an enhanced gate driver IC and Power Block Technology
to complete the power stage switching function. This combination produces a high current, high efficiency, high
speed switching device and delivers an excellent thermal solution in a small 5-mm × 6-mm outline package due
to its large ground based thermal pad. In addition, the PCB footprint has been optimized to help reduce design
time and simplify the completion of the overall system design.
