Overview

Maximizing IC Performance MT7285 Boost/Buck-Boost/Buck White LED Driver With High Frequency PWM Dimming DESCRIPTION The MT7285 is a constant current white LED driver designed for wide input voltage range from 4.
2V to 40V system rail.
The MT7285 can be configured as Buck, Boost and Buck-Boost topology.
The MT7285 drives up to 20W with AC12V/DC12V input voltage.
Current mode and fixed frequency operation provides fast transient response and eases loop stabilization.
With a current sense amplifier threshold of 205mV, the LED current is programmable with one external current sense resistor and the power loss is minimized.
The 450kHz operating frequency minimizes external inductor, input and ou...
