Description

The MCP1663 device is a compact, high-efficiency, fixed-frequency, non-synchronous step-up DC-DC converter which integrates a 36V, 400 mΩ NMOS switch. It provides a space-efficient high-voltage step-up power supply solution for applications powered by either two-cell or three-cell alkaline, Ultimate Lithium, NiCd, NiMH, one-cell Li-Ion or Li-Polymerbatteries.

Features

  • Modular Design for Easy Evaluation of Each Converter
  • Clearly Labeled Sub-Modules for Quick Identification
  • Pre-Configured Output Voltages for Typical Use Cases Building Block Solutions – Switchers User’s Guide User Guide © 2025 Microchip Technology Inc. and its subsidiaries DS50003984A - 2
  • Test Points and Connectors for Easy Measurement and Integration

Typical applications

  • Single-Cell Li-Ion to 5V, 12V or 24V Converters
  • Portable Medical Equipment
  • Two and Three-Cell Alkaline, Lithium Ultimate and NiMH/NiCd Portable Products, Hand-Held Instruments, LCD Bias Supply for Portable Applications
