MCP1630 自动输入三输出转换器演示板演示了Microchip 高速脉冲宽度调制器（PWM）在汽车中的应用。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 applicationFeatures:

       

• 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%
