MP9486AGN-Z

MP9486A is a high voltage, step-down, switching regulator that delivers up to 1A of continuous current to the load. It integrates a high side, high voltage, power MOSFET with a current limit of 3.5A, typically. The wide 4.5V to 100V input range accommodates a variety of step-down applications, making it ideal for automotive, industry and lighting applications. Hysteretic voltage-mode control is employed for very fast response. MPS’s proprietary feedback control scheme minimizes the number of required external components. The switching frequency can be up to 1MHz, allowing for small component size. Thermal shutdown and short-circuit protection (SCP) provide reliable and fault-tolerant operations. The MP9486A is available in a SOIC-8 package with an exposed pad. Applications include scooters, E-Bike control power supplies, solar energy systems, automotive system power, industrial power supplies and high power LED drivers.
