MAP3511 Average Current Control Buck Controller

MAP3511 is an 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 highside current sensing. MAP3511 features ±1% CS voltage accuracy and has dedicated analog dimming input u.
