    High-Voltage Step-Up LED Driver with UVLO and Open Load Protection
    Features General Description 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. 36V, 400 mпЃ— Integrated Switch
