INTRODUCTION
MCP1640 SHORT OVERVIEW
This chapter provides an overview of the MCP1640 12V/50 mA Two Cells Input Boost
Converter Reference Design and covers the following topics:
•
•
•
The MCP1640 device is a compact, high-efficiency, fixed frequency, step-up DC-DC
converter. It provides an easy-to-use power supply solution, with a minimum number of
external components, for applications powered by one-cell, two-cell, or three-cell
alkaline, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries.
The MCP1640/C device automatically selects the best operating mode for efficiency,
PWM (Pulse-Width Modulation) or PFM (Pulse Frequency Modulation). The
MCP1640B/D device is running in PWM mode only and is ideal for noise sensitive
applications. It has a low quiescent current (19 µA, PFM mode typical), a wide input
voltage range (0.35 to 5.5V) and a low start-up voltage (0.65V at 1 mA load current).
The MCP1640 device consumes less than 1 µA in Shutdown mode.
Microchip Technology Inc. provides the MCP1640 device in four variants, which help
engineers to meet different system requirements. The devices and their available
options are presented in
TABLE 1-1:
The MCP1640 is available in SOT23-6 and 8-LD DFN (2x3 mm) packages. For
additional information on the MCP1640 device, refer to the “MCP1640/B/C/D Data
Sheet” (DS22234).
