MP9487GN
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 shutdown and short-circuit protection (SCP) provide reliable and fault-tolerant operations. A 170µA quiescent current allows the MP9487 to be used in battery-powered applications.
The MP9487 is available in a SOIC-8 package with an exposed pad.
