產品總覽

The MCP1640RD-4ABC is a MCP1640 compact, high efficiency, fixed frequency, step up DC to DC converter reference design. 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. With the true output disconnect Shutdown option, works attached to a microcontroller application. This board demonstrates how to optimize battery life using the MCP1640, and an 8bit low cost PIC microcontroller, to reduce the no load input current for applications that operate in Standby mode for a long period of time. During Standby, the enable signal for the MCP1640 has a low frequency, with less than 1% positive duty cycle. This maintains the output of the MCP1640 device up to 2.3V, which is sufficient to keep the PIC microcontroller live. This solution reduces up to 80% of the No Load Input Current the MCP1640 consumes in PFM Mode.
  • Input voltage is provided by one AAAA alkaline battery
  • Output voltage is typically 3.3V
  • Output current is less then 130mA
  • Up to 75% efficiency
  • Standby battery current 14.5µA at 1.5V input
  • Low input start up voltage, typically 0.65V at 1mA load current
  • PWM switching frequency is 500KHz
  • MCP1640 device automatically selects the best operating mode for efficiency, PWM or PFM
  • LED status indication (Output ON and low battery)
  • Energizer battery holder with reverse battery protection
