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.","metaTitle":"Microchip MCP1640DT-I/CHY Boost Regulator, 350mA, SOT-23-6","metaDescription":"MCP1640DT-I/CHY step-up DC-DC converter, 350mA output, 500kHz switching, 0.8-5.5V input, SOT-23-6.
