MAP3613 is a 3 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.

MAP3613 features ±1% CS voltage accuracy and

has dedicated analog dimming input up to 3V. It can

be powered from 8.5V ~ 18V supply.

MAP3613 provides MOSFET DS short and free-

wheeling diode open detection(FLT output), sense

resistor short protection, SCP, ODP and UVLO.

MAP3613 is available 20 leads SOIC with Halogen-

free (fully RoHS compliant).
