MAP3622 – 2-CH Average Current Control Buck Controller for LED Backlight Datasheet Version 1.0 MAP3622 2-CH Average Current Control Buck Controller for LED Backlight General Description Features MAP3622 is a 2 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 compensation or high-side current sensing. MAP3622 features ±1% CS voltage accuracy and has dedicated Independent analog dimming input up to 3.3V. It can be powered from 8.5V ~ 18V supply. MAP3622 provides MOSFET DS short (FLT output), sense resistor short protection, SCP and UVLO.
