The TPS40091PWR from Texas Instruments is a high-frequency, multiphase synchronous buck controller optimized for high-current applications powered by a 5V to 15V distributed supply. This controller supports two-, three-, or four-phase operation, enabling lower current ripple, faster transient response, and improved power handling capabilities.
Key electrical specifications include an input voltage range of 4.5V to 15V and an output voltage range from 0.7V to 3.3V. It supports up to 1-MHz switching frequency per phase, with a maximum duty cycle of 87.5%. The device features current mode control with forced current sharing, a 1% internal 0.7V reference, and supports resistive or DCR current sensing. Control features include current limit, enable, frequency control, power good, and soft start.
The TPS40091PWR is available in a 24-TSSOP package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. This controller is ideal for applications such as internet servers, network equipment, and telecommunications equipment requiring efficient and robust power delivery.
