MCP1630 AUTOMOTIVE INPUT BOOST CONVERTER DEMO BOARD USER’S GUIDE Chapter 1. Product Overview 1.1 INTRODUCTION The proliferation of distributed power supplies is expected to accelerate their use in future generation cars. Distributed power supplies or "point-of-load" power supplies are being used increasingly throughout. These Power Supply Units (PSUs) are responsible for stepping up (or down) a 12V nominal bus, to power a multitude of subsystems.
MCP1630 Automotive Input Boost Converter Demo Board User’s Guide 1.2 WHAT IS THE MCP1630 AUTOMOTIVE INPUT BOOST CONVERTER DEMO BOARD? The MCP1630 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.
MCP1630 AUTOMOTIVE INPUT BOOST CONVERTER DEMO BOARD USER’S GUIDE Chapter 2. Installation and Operation 2.1 INTRODUCTION The MCP1630 Automotive Input Boost Converter Demo Board demonstrates Microchip's high-speed pulse width modulator used for automotive applications. When used in conjunction with a microcontroller, the MCP1630/V devices will control the power system duty cycle to provide regulated output voltage.
MCP1630 Automotive Input Boost Converter Demo Board User’s Guide 2.3 GETTING STARTED The MCP1630 Automotive Input Boost Converter Demo Board is fully assembled and tested for automotive input. The board requires the use of an external input voltage source (+9V to 18V) and external load. 2.3.1 Power Input and Output Connection 2.3.1.1 POWERING THE MCP1630 AUTOMOTIVE INPUT BOOST CONVERTER DEMO BOARD 1. Connect the positive side of the input source (+) to TP1. 2.
Installation and Operation 2.3.1.2 APPLY LOAD TO MCP1630 AUTOMOTIVE INPUT BOOST CONVERTER DEMO BOARD A variable resistive load can be used to verify the line and load regulation. The load resistance is connected between the points TP3 and TP4. To measure the output voltage, connect the common point of a multimeter to TP4 and the positive terminal to TP3. By varying the load, the load regulation can be verified by measuring the output voltage over the entire load range of 0 mA to 400 mA.
