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.
