MP4689


100V 1A Buck WLED Driver with Hysteretic Control

The MP4689 is a high voltage input step-down switching regulator to deliver a constant current of up to 1A to high power LEDs. It integrates a high-side high voltage power MOSFET with a current limit of 2.5A (typical value). The wide 4.5V to 100V input range accommodates a variety of step-down applications, making it ideal for automotive, industrial and general lighting applications. Hysteresis current mode control is applied for very fast response, which makes the 20kHz dimming frequency possible. MPS’s proprietary feedback control scheme minimizes the number of external components while delivering a LED current with typical ±3% accuracy. The switching frequency is up to 1MHz, thus allowing for small component size. The thermal shut down, short circuit protection, and optional output voltage limitation provide reliable, fault tolerant operations. A 170µA quiescent current allows its use in battery-powered applications.  The MP4689 is available in SOIC8 with exposed pad packages.
