TPS40090PW Description

Short technical summary and product information.

The TPS40090PW from Texas Instruments is a high-frequency, multiphase controller designed for DC-DC buck conversion. It supports two-, three-, or four-phase operation, optimizing for low-voltage, high-current applications powered by a 5V to 15V distributed supply.

 

This controller features current mode control with forced current sharing and a programmable switching frequency up to 1.2MHz per phase. It offers a 1% internal 0.7V reference and supports resistive or DCR current sensing with fault protection. The output voltage is set by a resistive divider, and it includes features like Enable, Power Good, and Soft Start.

 

The TPS40090PW is available in a 24-pin TSSOP package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA). The device is designed for applications such as internet servers, network equipment, and telecommunications equipment.

 

Key electrical specifications include an operating voltage range of 4.5V to 15V, a maximum duty cycle of 87.5%, and a switching frequency range of 100kHz to 1.2MHz. It provides a PWM signal output and is a non-synchronous buck controller.
