The Texas Instruments UCD9112RHBR is a highly integrated, high-performance DC-DC step-down controller designed for power management in demanding applications. This component features a flexible architecture supporting a single output phase with a PWM signal output type. It operates within a switching frequency range of 250kHz to 1MHz and offers a maximum duty cycle of 100%, facilitating efficient power conversion. Key control features include current limiting for robust operation, power good indication for system monitoring, and tracking capabilities for multi-rail sequencing. The UCD9112RHBR is housed in a 32-VQFN (5x5) exposed pad package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ), making it suitable for use in industrial and automotive sectors. The device requires a supply voltage between 3.14V and 3.46V.
