Datasheet Summary
100V Input, 3.5A, Switching Current Limit Step-Down Converter
DESCRIPTION
The MP9487 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 acmodates 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 ponents.
The switching frequency can be up to 1MHz, allowing for small ponent size. Thermal...
