The SC604A is a very high efficiency charge pump white LED driver driver from the mAhXLifeTM family of products, optimized for Li-Ion battery applications.
The four (4) LED outputs are current matched for consistent LED brightness. Extremely low battery current is achieved by automatically reconfiguring the charge pump to match circuit conditions. Using four LEDs, each at 20mA for a total IOUT= 80mA, the SC604A can use less than 83mA from the supply for most of the battery life. Patented low noise mode switching circuitry and constant output current allow the use of extremely small input and output capacitors.
