INTRODUCTION
FEATURES
Chapter 2. Installation and Operation
The MCP1630 Coupled Inductor Boost Converter Demo Board demonstrates
Microchip's High-Speed Pulse Width Modulator (PWM) used in a coupled inductor
design. When used in conjunction with a microcontroller, the MCP1630 device will
control the power system duty cycle to provide different regulated output voltages using
push button S1. The PIC12F683 microcontroller is used to generate oscillator pulses,
reference voltage and output voltage selection using push button S1. The PIC12F683
can also be programmed to monitor the board ambient temperature using the
MCP9700 Linear Active Thermistor™ device and provide different regulated output
voltages for different thermal readings. The MCP1630 device generates duty cycle
based on various external inputs. External signals include the input oscillator pulses,
reference voltage from PIC12F683 device, 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 device in this
application.
The MCP1630 Coupled Inductor Boost Converter Demo Board has the following
features.
• With reduced stress on the MOSFET switch, provides greater degree of freedom
• Provides a varied output voltage selection from 15V to 40V in steps of 5V
• Push button select option for the required output voltage selection and ON/OFF
• Tight line and load regulation and high efficiency over entire operating input
• PIC12F683 microcontroller is used to generate the Oscillator pulse and reference
