SD6209 丝印AX599 移动电源升压IC移动电源限流升压3V转5V/1A

General Description

The SD6209 is a boost topology switching regulator for wide operating voltage applications. Itprovides built-in gate driver pin, EXT pin, for driving the external N-MOSFET. The internal  compensation network minimizes external component counts, and the non-inverting input of error amplifier connects to a 0.6V precision reference voltage.The SD6209 internal soft start function.The SD6209 is available in the small footprint SOT23-5L package to fit in space-saving PCB layout for miscellaneous application fields.
