3-CH Average Current Control Buck Controller for LED Backlight
General Description
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).
