SNVS551E April 2008 – May 2016 LM2758
PRODUCTION DATA.
The LM2758 device is an integrated low-noise, high-current 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 time-out 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.
