Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DT' against official Microchip documentation to confirm tape-and-reel packaging status, as standard datasheets may list bulk or tube options. Ensure the 'I' temperature grade matches your environmental requirements. Cross-reference the exact part number with authorized distributors to confirm availability and authenticity before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a single-cell lithium-ion or alkaline battery source. The 800 mA output capability suits moderate load applications. Consider the MSOP package size for space-constrained designs. Verify that the 1 MHz frequency aligns with EMI constraints and inductor selection guidelines provided in the datasheet.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MCP1642 family of synchronous boost converters. It shares architectural similarities with other members like the MCP1640 and MCP1642 adjustable variants but is distinguished by its fixed 5 V output configuration. The family is designed for low-power portable electronics, offering a balance between performance, size, and cost.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include MCP1642T-ADJI/MS for adjustable output needs, though voltage regulation differs. MCP1640D-I/MC offers similar functionality with lower current capacity. Verify pin compatibility and thermal performance when substituting.
