Product Overview

The MCP1640BT-I/CHY is a compact, high-efficiency, fixed frequency, synchronous step-up DC-DC Converter. It provides an easy-to-use power supply solution for applications powered by either one-cell, two-cell or three-cell alkaline, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries. It provides very high efficiency through integration of the low resistance N-channel boost switch and synchronous P-channel switch. Low-voltage technology allows the regulator to start-up without high inrush current or output voltage overshoot from a low 0.65V input. High efficiency is accomplished by integrating the low resistance N-Channel boost switch and synchronous P-Channel switch. All compensation and protection circuitry is integrated to minimize the number of external components. For standby applications, it consumes only 19μA while operating at no load and provides a true disconnect from input to output while in shutdown (EN = GND).
  • Up to 96% typical efficiency
  • 0.35V Operating input voltage
  • Automatic PFM/PWM operation
  • PWM operation at 500kHz
  • 19µA Typical PFM mode low device quiescent current
  • <1µA Shutdown current (all states)
  • Internal synchronous rectifier
  • Internal compensation
  • Inrush current limiting and internal soft-start
  • True load disconnect shutdown
  • Low noise, anti-ringing control
  • Over-temperature protection
