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.

MAP3622 is available 16 leads SOIC with Halogen-

free (fully RoHS compliant).
