2-CH Average Current Control Buck Controller for LED Backlight
General Description
MAP3512 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.
MAP3512 features ±1% CS voltage accuracy and
has dedicated analog dimming input up to 3V. It can
be powered from 8.5V ~ 18V supply.
MAP3512 provides MOSFET DS short detection(FLT
output), SCP, ODP and UVLO.
MAP3512 is available 16 leads SOIC with Halogen-
free (fully RoHS compliant).
