The TPS40090PWG4 from Texas Instruments is a high-frequency, multiphase buck controller optimized for low-voltage, high-current applications. It supports two-, three-, or four-phase operation, enabling lower current ripple and faster transient response.
This controller features a wide operating voltage range of 4.5V to 15V and can achieve output voltages from 0.7V to 3.3V. The programmable switching frequency can be set up to 1.2MHz per phase, resulting in an effective ripple frequency of up to 4.8MHz in a four-phase configuration. It utilizes current mode control with forced current sharing for robust performance.
Key features include a 1% internal reference voltage, resistive divider set output voltage, true remote sensing, and resistive or DCR current sensing with fault protection. The TPS40090PWG4 is available in a 24-pin TSSOP package, suitable for surface mounting.
Applications for this controller include internet servers, network equipment, telecommunications equipment, and DC power distributed systems where efficient, high-current power delivery is critical.
