MAP3621
1-CH Average Current Control Buck Controller for LED Backlight
General Description
Features
MAP3621 is a single 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.
MAP3621 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.
MAP3621 provides
MOSFET DS short (FLT output), sense resisto...
