3 Description
The CSD967201-Q1 power stage is a highly
optimized design for use in an automotive qualified
high-power, high-density synchronous buck converter.
This device integrates the driver IC and power
MOSFETs into one Pb-free monolithic design to
complete the power stage switching function. This
combination produces high-current, high-efficiency,
and high-speed switching capability in a small industry
standard 5mm × 6mm × 0.75mm footprint.
CSD967201-Q1 integrates accurate current sensing
and temperature sensing functionality to simplify
system design and improve accuracy. Protections
include cycle-by-cycle overcurrent and negative
overcurrent limiting, overtemperature shutdown, HS
FET short, and UVLO on VCC, VIN, and BOOT.
The CSD967201-Q1 is compatible with the
TPS64300-Q1 VRS-11 controller, as well as other
standard VRS-11 controllers.
