High-efficiency LED flash power supply ICs are ideal for driving a single or multiple white LED flash in camera phones, PDAs and other handheld devices. The synchronous buck-boost topology with output current control guarantees the correct LED current over all possible conditions of battery level and LED forward voltage. Hard and soft triggering of the flash are supported. The devices include several functions to protect the chip and the power LEDs. These include soft-start control, over-temperature detection/protection and open and shorted LED detection/protection.
