The MCP1630 Boost Mode LED Driver Demo Board uses the following primary devices
on the board.
• A MCP1702 LDO regulator is used to supply the regulated voltage to the
• A MCP1630, a high-speed pulse width modulator IC, is used. When used in
• A PIC12F683 microcontroller (MCU) is used to generate the MCP1630 reference
• Input Voltage: +9V to 16V
• Maximum Output Voltage: 50V (limited to 40V by application software)
• Typical Output Current: 700 mA
• Maximum Output Current: 1A
• Maximum Output Power: 30W

PIC12F683 and the MCP1630. The MCP1702 is capable of delivering 250 mA
with only 650 mV (typical) of input to output voltage differential
conjunction with a microcontroller, the MCP1630 will control the power system
duty cycle to provide output current and/or voltage regulation
voltage and the oscillator signal at 500 kHz
