MCP1630 AUTOMOTIVE INPUT TRIPLE OUTPUT CONVERTER DEMO BOARD
- Compact size for a Triple output Converter
- Wide Input voltage range from 6.5V to 40V
- Output voltage ON/OFF control using the PIC microcontroller
- Provide line regulation, load regulation and cross regulation of ±5% on VOUT1 (3.3V), ± 5% on VOUT2 (1.2V) and ±10% on VOUT3 (4.7V) for load variation from 50% to 100%
Overview
This product is no longer available for sale.
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 three regulated output voltages of 3.3V at 1.2A, 1.2V at 600mA and 4.7V at 150 mA. The PIC12F683 microcontroller is used to provide reference voltage, ON/OFF of Converter using push button SW1 and oscillator pulses at switching frequency of 250 kHz. The MCP1630 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 PIC12F683 microcontroller is programmable, allowing the user to modify or develop their own firmware routines to further evaluate the MCP1630 device in this application
