Miniaturized, power-efficient backlighting solution in PCB footprint

The NCP5007 and NCP5006 are fully integrated white LED boost converters that drive up to five white LEDs in series to simplify and miniaturize color LCD display illumination used in digital cameras, cell phones and PDAs.



Converters simplify and miniaturize color LCD display.

These devices by ON Semiconductor operate as dc/dc boost converters that regulate the current through the LED string. Offered in a compact, low-profile SOT23-5 package, the NCP5007 and NCP5006 incorporate built-in overvoltage protection that eliminates the need for an external zener diode. This works to simplify and miniaturize the circuit. With an input voltage range of 2.7 to 5.5V, the devices are ideal for battery power applications that use 1-cell Li-ion battery or 3/4-cell NiMH batteries.
