  • Page 10: What Is The Mcp1630 Automotive Input Triple Output Converter Demo Board

    SEPIC topology for Automotive applications. The board also serves as a platform to evaluate the MCP1630 device. The MCP1630 inputs were developed to be easily attached to the I/O of a MCU. The MCU supplies the oscillator pulses and reference voltage (V ) to the MCP1630 to provide the most flexible and adaptable power system.

  • Page 11: Chapter 2. Installation And Operation

    The MCP1630 Automotive Input Triple Output Converter Demo Board demonstrates Microchip's high speed pulse width modulator (PWM) used for Automotive application. When used in conjunction with a microcontroller, the MCP1630 will control the power system duty cycle to provide regulated output voltage. The PIC12F683 microcontroller is used to provide oscillator pulses at switching frequency of 250 kHz and set maximum duty cycle.
