Boost White LED Driver With High Frequency PWM Dimming
DESCRIPTION
The MT7261 is a Boost constant current white LED driver designed for wide input voltage range from 2.5V to 30V system rail, drives up to 7X1W power 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 550KHz operating frequency minimizes external inductor, input and output capacitor. The MT7261 supports both PWM and analog dimming by a single...
