How the MCP1664 click works
The click has a power input and a PWM input, so you can set the light intensity at the level you want.
MCP1664 IC features
The MCP1664 is a compact, space-efficient, fixed-frequency, non-synchronous step-up converter optimized to drive multiple strings of LEDs with constant current powered from two and three-cell alkaline or NiMH/NiCd as well as from one-cell Li-Ion or Li-Polymer batteries.
The MCP1664 features an open load protection (OLP) which turns off the operation in situations when the LED string is accidentally disconnected or the feedback pin is short-circuited to GND.
While in Shutdown mode (EN = GND), the device stops switching and consumes 40 nA typical of input current.
