3 Description
The TPS564201 is a simple, easy-to-use, 4-A
synchronous
step-down
converter
in
SOT-23
package.
The device is optimized to operate with minimum
external component count and also optimized to
achieve low standby current.
These switch mode power supply (SMPS) devices
employ D-CAP2 mode control providing a fast
transient
response
and
supporting
both
low-
equivalent series resistance (ESR) output capacitors
such as specialty polymer and ultra-low ESR ceramic
capacitors
with
no
external
compensation
components.
The TPS564201 operates in pulse skip mode,
maintaining high efficiency during light load operation.
The TPS564201 is available in a 6-pin 1.6-mm × 2.9-
mm SOT (DDC) package, and specified from a –40°C
to 125°C junction temperature.
