Quality Control: Learn More
The Texas Instruments TPS40091RHDT is a versatile 4-phase synchronous buck controller. This device is designed for step-down DC-DC conversion, offering a positive output configuration with a maximum duty cycle of 87.5%. It operates with a wide supply voltage range of 4.5V to 15V and supports switching frequencies from 100kHz up to 1.2MHz. Key control features include current limit, enable, frequency control, power good, and soft start, facilitating robust power management. The TPS40091RHDT is housed in a 28-VQFN (5x5) package, surface mounted, and is supplied on tape and reel. Its multi-phase architecture makes it suitable for applications requiring high current and efficient power delivery in automotive, industrial, and communication systems.
