Texas Instruments TPS40140RHHR is a dual-output, synchronous buck controller designed for efficient step-down DC-DC conversion. Operating from a 4.5V to 15V supply, this device features a selectable switching frequency range of 150kHz to 1MHz, offering flexibility in component selection and power density optimization. The TPS40140RHHR supports two output phases and incorporates advanced control features including current limit, frequency control, phase control, and power good indication. Its transistor driver output type and synchronous rectification capability contribute to high efficiency. This surface mount component is housed in a 36-VQFN (6x6) package, supplied on tape and reel. Applications include power supplies for computing, industrial, and consumer electronics.
