TPS40090PWR Description

Short technical summary and product information.

The TPS40090PWR from Texas Instruments is a high-frequency, multiphase synchronous buck controller optimized for low-voltage, high-current applications powered by a 5V to 15V distributed supply. This controller supports two-, three-, or four-phase operation, offering advantages such as lower ripple, faster transient response, and improved power handling.

 

Key electrical specifications include an input voltage range of 4.5V to 15V and a programmable switching frequency of up to 1.2MHz per phase. It features current mode control with forced current sharing, a 0.7V internal reference, and supports resistive or DCR current sensing. The device is configured for 4 output phases and operates as a step-down (buck) converter.

 

Packaged in a 24-TSSOP, the TPS40090PWR is designed for surface mount applications. Its operating temperature range is -40°C to 85°C (TA). The controller includes features like current limit, enable, frequency control, power good, and soft start, making it suitable for demanding power distribution systems.
