Sketch
The BP1618 is a two-string step-up LED driver for wide input/output voltage range with a boost power switch integrated inside. The BP1618 employs peak current mode, fixed frequency architecture to provide robust operation with minimum 3V input supply. The switching frequency is programmable by an external frequency setting resistor.
