FEATURES
DEVICE SUMMARY
The MCP1630 Sepic Automotive LED Driver Reference Design has the following
features:
• Compact size with high output power
• Can operate in Buck (step-down) or Boost (step-up) mode
• Sustains voltage stresses typically found in automotive products:
• High efficiency over the entire operating input and output voltage ranges:
• Maximum Output Current = 350 mA; this value can be modified with minor
• Maximum Output Power = 18W
• Optional software dimming control for both methods: PWM or Current mode
• Preprogrammed source code
• The switching frequency, maximum duty cycle and the MCP1630 reference
• Additional application functions can be implemented in firmware
The MCP1630 Sepic Automotive LED Driver Reference Design uses the following
devices:
• MCP1630 High-Speed Pulse-Width Modulator IC – When used in conjunction with
• PIC12F683 Microcontroller (8-bit MCU) – Used to generate the MCP1630’s
• MCP1790 HV LDO Regulator – Used to supply the regulated voltage to the
