MAP3205
4-channel LED Driver for High Brightness LEDs
General Description
The MAP3205 is a 4-channel LED driver optimized
for LED backlight application targeting mid and large
size LCD module. It uses the boost MOSFET
externally and 4-channel current sources internally for
driving high brightness white LEDs.
Input voltage of the MAP3205 is ranged from 8V to
36V and max. LED current is 150mA per channel. It
can increase the output voltage depending on the
drain voltage rating of boost MOSFET.
It features PWM dimming control, internal soft-start
and has unique adaptive internal OVP, boost MOSFET
OCP, LED short/open protection, SBD open protection
and UVLO.
