Overview
MP9486A is a high-voltage step-down switching regulator that can provide up to 1A of continuous current to loads. It integrates high-voltage power MOSFET, with a typical current limit of 3.5A. The wide input range of 4.5V to 100V is suitable for various voltage reduction applications, making it ideal for automotive, industrial, and lighting applications. Adopting hysteresis voltage mode control, the response speed is extremely fast. The proprietary feedback control scheme of MPS minimizes the required number of external components to the greatest extent possible. The maximum switching frequency can reach 1MHz, allowing the use of small-sized components. The thermal shutdown and short circuit protection (SCP) function ensures that
