TPS40132RHBR Description

Short technical summary and product information.

The TPS40132RHBR from Texas Instruments is a two-phase synchronous buck controller optimized for high-current applications powered by a supply between 4.5V and 28V. This controller features two output phases operating 180 degrees out-of-phase, which offers advantages such as lower current ripple and faster transient response compared to single-phase converters.

 

Key electrical specifications include a wide operating voltage range of 4.5V to 28V and a programmable switching frequency from 100kHz up to 1.2MHz per phase. The device supports up to two outputs and features control functions like current limit, enable, frequency control, power good, and soft start. It also includes a synchronous rectifier for improved efficiency.

 

The TPS40132RHBR is housed in a 32-VQFN (5x5) package with exposed pad, designed for surface mounting. The operating temperature range is -40°C to 85°C (TA). The controller is suitable for applications requiring efficient voltage regulation and high output current capabilities.
