MCP1630 Automotive Input Triple Output Converter Demo Board User’s Guide

1.2 WHAT IS THE MCP1630 AUTOMOTIVE INPUT TRIPLE OUTPUT CONVERTER

DEMO BOARD?

The MCP1630 Automotive Input Triple Output Converter Demo Board demonstrates

the use of a SEPIC topology for Automotive applications. The board also serves as a

platform to evaluate the MCP1630 device.

The MCP1630 inputs were developed to be easily attached to the I/O of a MCU. The

MCU supplies the oscillator pulses and reference voltage (V

REF

) to the MCP1630 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 high speed PWM can be external, a D/A Converter (DCA) 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 utilizes Microchip's MCP1630 (High-Speed, Microcontroller-Adaptable,

PWM MSOP8) integrated with PIC12F683 (Flash MCU SOIC8) in automotive

application. Under normal operation, the supply lines can range between 6.5V - 40V.

The converter is capable of delivering three different output voltages of 3.3V at 1.2A

load current, 1.2V at 600 mA load current and 4.7V at 150 mA load current, respec-

tively. The Line regulation, Load regulation and Cross regulation is within ± 5% on

OUT1

, ± 5% on V

OUT2

and ± 10% on V

OUT3

for the variation in load from 50% to 100%.
