TPS40422RSBR Description

Short technical summary and product information.

The Texas Instruments TPS40422RSBR is a versatile dual-output or two-phase synchronous buck controller designed for efficient power management. It features a PMBus interface for digital control and monitoring, enabling advanced configuration and diagnostics.

 

This controller supports a wide input voltage range of 4.5V to 20V and can deliver output voltages from 0.6V to 5.6V. Key electrical specifications include a programmable switching frequency from 200 kHz to 1 MHz, a 600mV reference voltage with ±0.5% accuracy, and support for inductor DCR current sensing. The device operates out-of-phase by 180° to minimize input ripple and offers features like output voltage and current monitoring, external temperature monitoring, and programmable UVLO thresholds.

 

Packaged in a 40-WQFN (5x5) surface-mount package, the TPS40422RSBR is suitable for various applications requiring precise and flexible DC/DC conversion. Its design considerations include voltage mode control with input feed-forward, current sharing for multiphase operation, and support for pre-biased outputs and differential remote sensing.
