TPS40422RHAR Description

Short technical summary and product information.

The Texas Instruments TPS40422RHAR is a versatile DC/DC switching controller designed for dual-output or two-phase synchronous buck applications. It features a wide input voltage range of 4.5V to 20V and supports output voltages from 0.6V to 5.6V.

 

This controller integrates a PMBus interface for advanced control and monitoring capabilities, including dynamic voltage scaling and programmable fault response. Key electrical specifications include a maximum output current of 60A and a switching frequency adjustable from 100kHz to 1MHz. The device operates with a typical quiescent current of 0.018A and a maximum duty cycle of 90%.

 

Designed for surface mount, the TPS40422RHAR is available in a 40-VQFN (6x6 mm) package. Its operating temperature range is -40°C to 125°C (TJ). The controller supports features such as frequency synchronization, phase interleaving, and remote sensing, making it suitable for power management solutions requiring high efficiency and precise regulation.
