6-Channel Fractional Charge Pump LED Driver
w h i t e l e d d r i v e r s
CAT3606
Features
■
independent dimming and standby control
for Main and Sub displays
■
automatically switches from 1x LDO mode to
1.5x boost mode
■
inductor-less design minimizes EMI
interference
■
drives up to 6 Parallel LEDs at 30mA per
channel
■
very low input ripple and noise
■
“zero” shutdown current extends battery life
■
power efficiency up to 90%
■
short circuit detect/disable on all channels
■
optimized for use with Lithium-Ion battery systems
