Description

The STCF04 is a dedicated and space optimized

high efficiency solution for driving a flash LED

module in cameras, phones, PDAs and other

handheld devices using the SuperCap

technology. It is based on a DC-DC buck-boost

converter, which ensures a proper and efficient

charging control and monitoring of the SuperCap

in the whole battery voltage range. The output

current control ensures a good current regulation

over the forward voltage spread characteristics of

the flash LEDs in Torch and Flash mode

operation. The SuperCap charging current is

limited to a defined value which avoids overload of

the battery. The SuperCap discharge current

flows through the LEDs and the external

MOSFET which must be chosen according to the

desired flash current.
