3 Description

The LM2758 device is an integrated low-noise, highcurrent

switched capacitor DC-DC converter with a

regulated current sink. The device is capable of

driving loads up to 700 mA from a single-cell Li-Ion

battery. Maximum efficiency is achieved over the

input voltage range by actively selecting the proper

gain based on the LED forward voltage and current

requirements.

One external low-power resistor sets the desired

current for indicator, torch, and flash modes. To

protect the devices and the flash LED, internal timeout

circuitry turns off the LM2758 in case of a faulty

prolonged flash mode. Internal soft-start circuitry

limits the amount of inrush current during start-up.
