com LM27953 White LED Driver with Four LED Current Sinks and 3/2x Switched Capacitor Boost LM27953 White LED Driver with Four LED Current Sinks and 3/2x Switched Capacitor Boost General Description The LM27953 is a charge-pump-based white-LED driver that is ideal for mobile phone display backlighting.
It is intended to drive 4 LEDs for a main phone display backlight.
Regulated internal current sources deliver excellent current and brightness matching in all LEDs.
The LED driver current sinks can be used to backlight a main phone display with up to 4 LEDs.
The low-side current drivers accommodate common-anode-type LEDs.
The current sinks can also drive standard...
