Chapter 1. Product Overview

1.1 INTRODUCTION

This chapter provides an overview of the MCP1632 300 kHz Boost Converter Demo

Board and covers the following topics:

• Short Overview: MCP1632 PWM Controller

• What is the MCP1632 300 kHz Boost Converter Demo Board?

• What is Contained In the MCP1632 300 kHz Boost Converter Demo Board Kit?

1.2 SHO RT O VERVIEW : MCP1632 PW M CO NT R OLLE R

The MCP1632 is a high-speed, Current Mode PWM controller intended for applications

that require low-side MOSFET control, such as the Boost, Flyback or SEPIC

converters. The MCP1632 converter integrates all the blocks necessary to develop a

standalone switch-mode power supply. The MCP1632 PWM controller offers great

flexibility to designers, as the power train can be tailored for various applications and

power levels. The MCP1632 converter includes: internal oscillator with two options for

switching frequency (300 kHz and 600 kHz), adjustable reference voltage generator

and adjustable soft-start time, internal ramp generator for slope compensation and

blanking circuit for current sense (CS) signal, and an Undervoltage Lockout circuit

(UVLO). The MCP1632 PWM converter can be easily interfaced with PIC®

microcontrollers in order to develop intelligent solutions. The MCP1632 converter

accepts input bias voltages between 3V and 5.5V. For larger input voltages, a linear

voltage regulator can be used to provide the necessary bias voltage.

Typical applications include: general purpose DC-DC converters, LED drivers,

batteries chargers and bias generators.

1.3 WHAT IS THE MCP1632 300 KHZ BOOST CONVERTER DEMO BOARD?

The MCP1632 300 kHz Boost Converter Demo Board is a compact, highly efficient,

step-up voltage converter that will convert the input voltage rail (typically 5V) to a

regulated 12V output voltage. The maximum output current for this demo board is 0.9A.

The board demonstrates the capabilities of the MCP1632 PWM controller. Test points

for various signals are provided for measuring different parameters of the converter.

The demo board can be modified to support output voltages from 9V to 15V by

changing a single resistor.

Chapter 2. Installation and Operation

2.1 INTRODUCTION

The MCP1632 300 kHz Boost Converter Demo Board was developed to provide a

compact, low-cost and highly efficient step-up conversion for low output currents.

The key features of this board include:

• Input Voltage Range: 3.6V to 5.5V

• Output Voltage: 12V (can be adjusted between 9V and 15V by changing a single

resistor)

• Maximum Output Current: 0.9A

• 90% typical efficiency at 12V/0.8A output and 5V input

• 300 kHz fixed switching frequency

• Overcurrent Protection for MOSFETs

• Shutdown input for placing the converter in low-power Standby mode

• Undervoltage Lockout (UVLO) with 2.7V (Off) and 2.8V (On) typical thresholds

2.2 GETTING STARTED

The MCP1632 300 kHz Boost Converter Demo Board is fully assembled and tested to

evaluate and demonstrate the capabilities of the MCP1632 PWM controller.

2.2.1 Necessary Instruments and Tools

• Adjustable DC Power Supply with 0V-6V/5 ADC range output capability

• Electronic load with at least 1A current capability and load stepping capability

• Digital Oscilloscope with a minimum bandwidth of 50MHz

• Digital voltmeter/ammeter

• Optionally, a Network Analyzer/Bode Plot Analyzer for loop analysis

• Wires for connections; these wires must sustain high current, 4A for the

connection between adjustable DC power supply and board, 1A for the

connection between the board and the electronic load

2.2.2 Setup procedure

To power up the MCP1632 300 kHz Boost Converter Demo Board, the following steps

must be completed:

1. Connect the Electronic Load to J3 connector of the demo board; the “Positive”

(+) and “Negative” (-) connector pins are marked on the board silkscreen.

2. Connect the Adjustable DC Power Supply to J1 connector of the demo board; the

“Positive” (+) and “Negative” (-) connector pins are marked on the board

silkscreen.

3. The DC voltage supplied by the Adjustable DC Power Supply must be between

3.6V and 5.5V.

2.2.3 Board Testing

The typical testing setup is depicted in Figure 2-1. Table 2-1 shows all the available test

points on the board.

The user can connect various instruments at the listed test points to evaluate the

parameters of the converter. The typical performance data, curves and waveforms are

presented in Appendix C. “Typical Performance Data, Curves and Waveforms”.

Note that some parameters vary with the input voltage (e.g., the maximum output

current should not exceed 0.8A if the input voltage is below 4 V).

2.2.3.1 ADJUSTING THE OUTPUT VOLTAGE

The output voltage can be modified by changing the value of R8 from the feedback

divider. The output voltage is set according to Equation 2-1.

EQUATION 2-1: OUTPUT VOLTAGE

Do not modify the value of the R3 resistor (20 kΩ) because this will affect the loop

compensation of the system.

Some parameters, such as efficiency, the overcurrent protection thresholds and the

input and output voltage ripple, can be affected by the modification of the output

voltage.

Table 2-2 shows the standard value of the R8 resistor for several common output

voltages.
