open-in-new Find other Buck converters (integrated switch)


The TPS54J061 device is a high-efficiency, small-sized, synchronous buck converter with an adaptive on-time D-CAP3™ control mode. The device offers ease-of-use and low external-component count for space-conscious power systems.

This device features high-performance integrated MOSFETs, accurate ±1% 600-mV reference with an junction temperature range between –40°C and +125°C. Competitive features include very-low external-component count, fast load-transient response, accurate load regulation and line regulation, auto-skip or FCCM mode operation, adjustable soft-start control, and external compensation is not needed to support all ceramic capacitor design .

TPS54J061 is available in a 14-pin QFN package.
