MAP3621 Description
Features MAP3621 is a single channel average-mode current control buck controller for LED backlight application. It does not require an additional dimming MOSFET and utilizes constant off-time control and average current control feedback without external loop pensation or high-side current sensing. MAP3621 features ±1% CS voltage accuracy and has dedicated Independent analog dimming input up to 3.3V.
