SP6685
SP6685 is 700mA Buck/Boost Charge Pump LED Driver manufactured by Exar.
DESCRIPTION
The SP6685 is a current-regulated charge pump ideal for powering high brightness LEDs for camera flash applications. The charge pump can be set to regulated two current levels for FLASH and TORCH modes. The SP6685 automatically switches modes between step-up and step-down ensuring that LED current does not depend on the forward voltage. A low current sense reference voltage (50m V) allows the use of small 0603 current sensing resistors. The SP6685 is designed to operate from a single cell lithium-ion battery or fixed 3.3V or 5.0V power rails and is available in a Ro HS pliant, “green”/halogen free space saving 10-pin 3mmx3mm DFN package.
