TPS51222RTVR Description

Short technical summary and product information.

The TPS51222RTVR from Texas Instruments is a fixed-frequency, 99% duty cycle peak current-mode notebook system power controller. This device functions as a synchronous dual-output buck controller, supporting an input voltage range of 4.5V to 32V and offering output voltages from 1V to 12V.

 

Key electrical specifications include a wide operating frequency range of 200 kHz to 1 MHz, a maximum duty cycle of 99%, and a typical quiescent current of 0.0008A. The controller features include enable, frequency synchronization, light-load efficiency, phase interleaving, power good output, and synchronous rectification. It supports selectable light load operation modes such as Continuous, Auto Skip, and Out-Of-Audio Skip.

 

Packaged in a 32-WQFN (5x5 mm) format, the TPS51222RTVR is designed for surface mount applications. It includes programmable droop compensation, voltage servo, and adjustable soft start. Protection features include OCL/OVP/UVP/UVLO and non-latch thermal shutdown. The controller also offers current sensing via resistor or inductor DCR, a current monitor output for each channel, and an adaptive zero crossing circuit.
