in LM2758 Switched Capacitor Flash LED Driver in micro SMD October 9, 2009 LM2758 Switched Capacitor Flash LED Driver in micro SMD General Description LM2758 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 singlecell 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 ...
