LED flasher circuit using ADP1655 driver

This LED flasher circuit is made using ADP1655 driver ic manufactured by Analog Device
The ADP1655 integrates a 2 MHz synchronous inductive boost convertor, an I2C-compatible interface and a 500 mA current source.
The I2C-compatible interface enables the programmability of timers, currents, and status bit readback for operation monitoring and safety control.

The high switching frequency enables the use of a tiny, low profile 2.2 μH power inductor, and the current source permits LED cathode grounding for thermally enhanced, low EMI and compact layouts.
