MAP3612
2-CH Average Current Control Buck Controller for LED Backlight
General Description
Features
MAP3612 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 highside current sensing.
MAP3612 features ±1% CS
voltage accuracy and has dedicated analog dimming input up to 3V. It can be powered from 8.5V ~ 18V supply.
MAP3612 provides
MOSFET DS short detection(FLT output), SCP, ODP and UVLO.
MAP3612 is available 16 leads SOIC with Halogenfree (fully RoHS compliant).
