PRELIMINARY OVERVIEW AA1700 Constant Current White LED driver The AA1700 is a high frequency boost DC/DC converter with constant current output that drives white LEDs or similar. The LED current is set with the external resistor. Soft start circuitry prevents excessive current drawn from the supply during power on. Any number of LEDs can be connected in series as long as the summed forward voltages do not lead to exceed the specified operating output voltage range. This IC works with a wide operating supply range (1.8V to 15V) and low current consumption, is optimal for use in high-efficiency white LED driver. FEATURES • Drives Up to 8 LEDs in Series. • Second or more string of LEDs can be added. • Low current consumption: Typically 5.
