Boost converter parametric envelope
The MCP1640DT-I/CHY: This is a single-output step-up (boost) regulator with synchronous rectification, switching at 500 kHz — the rectifier is integrated, so no external Schottky diode is needed for the typical boost topology. Input range spans 0.8 V minimum to 5.5 V maximum — the 0.8 V undervoltage lockout lets it start from a nearly depleted single-cell alkaline or NiMH battery and keep running as the cell drains.
Temperature grade and deployment context
The SOT-23-6 package (Supplier Device Package SOT-23-6) is a standard surface-mount footprint — the 0.95 mm pitch and 2.9 mm body length suit compact two-layer PCBs where board space is the constraint.
Compliance and supply format
Cut Tape is available for prototype or low-quantity builds.
