MP8638GQ-Z

MP8638GQ-Z is a 16V, 12A, synchronous step-down converter with adjustable current limit. It is a fully integrated, high frequency, synchronous, rectified, step-down switch-mode converter. It offers an ultracompact solution that can achieve up to 12A of continuous output current (IOUT), with an adjustable current limit (ILIMT). MPS’s proprietary switching loss reduction technique and internal, low on resistance power MOSFETs allow the device to operate at high efficiency across the entire IOUT load range. Adaptive constant-on-time (COT) control mode provides fast transient response and eases loop stabilization. The DC auto-tune loop and remote differential sense provides good load and line regulation. Typical applications are telecommunication systems, networking systems, servers, cloud computing, and storage, general-purpose Point-of-Load (POL) systems, base stations, 12V distribution power systems, high-end televisions, game consoles and graphic cards.
