The TPS40041DRBR is a synchronous buck DC/DC controller with low input voltage (32V) manufactured by Texas Instruments. This controller uses two PMOS transistors to regulate output voltage as needed and provides isolated feedback and low output noise. It has voltage mode control and current mode protection with an adjustable current limit. The power supply can also be monitored with an integrated digital power monitor, providing the ability to measure input/output current, as well as input/output power. Additionally, this controller integrates bootstrap diodes, synchronous diodes, and a cycle-by-cycle peak current protection. This all-in-one device is ideal for use in applications such as automotive, portable, and industrial.
