INTRODUCTION
FEATURES
Chapter 2. Installation and Operation
The MCP1630 Automotive Input Boost Converter Demo Board demonstrates
Microchip's high-speed pulse width modulator used for automotive applications. When
used in conjunction with a microcontroller, the MCP1630/V devices 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 500 kHz
and set maximum duty cycle. The MCP1630/V devices generate duty cycles based on
various external inputs. External signals include the input oscillator pulses from
PIC12F683, the reference voltage and the feedback voltage. The output signal is a
square wave pulse given to drive the MOSFET.
The PIC12F683 microcontroller is programmable, allowing the user to modify or
develop their own firmware routines to further evaluate the MCP1630/V devices in this
application.
The MCP1630 Automotive Input Boost Converter Demo Board has the following
features:
• Compact size for an output power of 14.6W
• Tight line and load regulation and high efficiency over entire operating input
• PIC12F683 is used to generate reference voltage and oscillator signal at 500 kHz
• Proprietary features can be added by modifying the firmware contained in the
• Factory programmed source code is available
