TPS40091PW Description

Short technical summary and product information.

The Texas Instruments TPS40091PW is a high-frequency, multiphase controller optimized for low-voltage, high-current applications powered by a 5V to 15V distributed supply. This device supports two-, three-, or four-phase operation, offering advantages such as lower current ripple, faster transient response, and improved power handling capabilities.

 

Key electrical specifications include an operating voltage range of 4.5V to 15V and a programmable switching frequency up to 1.2MHz per phase. The controller features current mode control with forced current sharing, a 1% internal 0.7V reference, and resistive divider set output voltage. It also includes true remote sensing differential amplifier capabilities and resistive or DCR current sensing with fault protection.

 

The TPS40091PW is available in a 24-TSSOP package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA). The controller supports features like current limit, enable, frequency control, power good, and soft start, making it versatile for various power management designs.

 

This multiphase buck controller is well-suited for applications in internet servers, network equipment, telecommunications equipment, and DC power distributed systems where efficient and stable high-current power delivery is critical.
