Texas Instruments TPS40490MHRHDR is a highly integrated, synchronous buck controller designed for efficient step-down DC-DC power conversion. This device operates from a wide input voltage range of 6V to 60V, making it suitable for demanding applications. It features a flexible switching frequency, configurable from 100kHz up to 5.4MHz, and supports clock synchronization for precise timing control. The TPS40490MHRHDR offers comprehensive control features including adjustable current limit, dead-time control, enable functionality, frequency control, power good indication, and soft-start for robust power sequencing. Its output configuration supports a single positive voltage with a transistor driver output. The component is housed in a 28-VQFN (5x5) package with an exposed pad for enhanced thermal performance and is supplied on tape and reel. This controller is widely utilized in industrial power supplies, automotive systems, and high-performance computing.
