MCP1662 Description
The MCP1662 device is a pact, space-efficient, fixed-frequency, non-synchronous step-up converter optimized to drive LED strings with constant current from a two- or three-cell alkaline or lithium Energizer®, or NiMH/NiCd, or one-cell Lithium-Ion or Li-Polymer batteries. The device integrates a 36V, 800 m low-side switch, which is protected by the 1.3A cycle-by-cycle inductor peak current limit operation. All...
