MCP1630DM-DDBS1 Datasheet PDF - Microchip

The MCP1630 is a automotive input boost converter demo board demonstrates the use of a conventional boost topology with automotive input. The board also serves as a platform to evaluate the MCP1630/V devices. The MCP1630/V inputs were developed to be easily attached to the I/O of a microcontroller. The MCU unit supplies the oscillator pulses and reference voltage (VREF) to the MCP1630/V devices to provide the most flexible and adaptable power system. The power system switching frequency and maximum duty cycle are set using the I/O of the MCU. The reference input to the high speed PWM can be external, a D/A Converter output or as simple as an I/O output from the MCU. This enables the power system to adapt to many external signals and variables in order to optimize performance and facilitate calibration. This board utilises MCP1630/V integrated with PIC12F683 in automotive input application. Under normal operation, the vehicle voltage at the supply lines ranges between 9V to 18V.
