MT7200
Overview
The MT7200 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The device operates from an input supply between 7~40V and provides an externally adjustable output current of up to 350mA.
- Pass 4KV ESD test Simple low parts count 350mA output current Single pin on/off and brightness control using DC voltage or PWM Internal PWM filter Soft-start High efficiency (up to 97%) Wide input voltage range: 7V to 40V Output shutdown Up to 1MHz switching frequency Inherent open-circuit LED protection Typical 4% output current accuracy
