Featuring adjustable overvoltage protection, the device can drive one or more high-current flash LEDs in series in high or lower power modes controlled by an internal register or the FEN pin. It is a fixed-frequency, step-up DC-DC converter with two regulated current sinks, driving loads of up to 1.2 A from a single-cell lithium-ion battery. The driver has applications in mobile phones, personal digital assistants, portable scanners and medical strobe lights.
