MCP1642B/D TWO-CELL TO USB POWER EVALUATION BOARD USER’S GUIDE Chapter 1. Product Overview 1.1 INTRODUCTION This chapter provides an overview of the MCP1642B/D Two-Cells to USB Power Evaluation Board and covers the following topics: • MCP1642B/D Short Overview • What is the MCP1642B/D Two-Cells to USB Power Evaluation Board? • What the MCP1642B/D Two-Cells to USB Power Evaluation Board Contains 1.2 MCP1642B/D SHORT OVERVIEW The MCP1642B/D are compact, high-efficiency, fixed-frequency, step-up DC-DC converters. These products provide an easy-to-use power supply solution, with a minimum number of external components for applications powered by one-cell, two-cell, or three-cell alkaline, Ni-Cd, Ni-MH, one-cell Li-Ion or Li-Polymer batteries. The MCP1642B/D devices operate in Pulse-Width Modulation (PWM), at a fixed 1 MHz switching frequency, featuring Internal Compensation, Overtemperature Protection and Power Good Open-Drain Output. The device has 1.8V start-up voltage at 5V output and 1 mA load current. There are two shutdown options for the MCP1642B/D family: • True Output Disconnect mode (MCP1642B/D) • Input-to-Output Bypass mode (MCP1642D) For the fixed-output voltage option of the MCP1642B/D devices, the VFB pin is not connected. The output voltage is set by an internal feedback divider. The fixed values are: 1.8V, 3.0V, 3.3V, 5.0V (see Table 1-1). On the MCP1642B/D Two-Cells to USB Power Evaluation Board, the fixed output voltage version (MCP1642B/D-50) is used. The goal of the MCP1642B/D Two-Cells to USB Power Evaluation Board is to demonstrate the higher output current capabilities of the MCP1642B/D, supplied from two AA batteries.

The MCP1642B/D Two-Cells to USB Power Evaluation Board is used to evaluate and demonstrate Microchip Technology’s MCP1642B/D/D Switching Boost Regulator. This board demonstrates the MCP1642B/D capabilities in a boost-converter application supplied from two AA batteries or from an external voltage source. A USB cable can be connected to the output of MCP1642B/D Two-Cells to USB Power Evaluation Board and used to provide power to portable electronic devices when necessary. It can be used to evaluate the MSOP-8 package. The MCP1642B/D Two-Cells to USB Power Evaluation Board was developed to help engineers reduce the product design cycle time. On the MCP1642B/D Two-Cells to USB Power Evaluation Board, the output voltage has the value of 5.0V (the fixed value MCP1642B/D-50 device is used), resulting in a simple and compact application. The footprints for RT and RB (resistor divider connected to the FB pin) are not populated and will only be used if MCP1642B/D-ADJ, the adjustable option, will be tested. An enable (EN Switch selection) is used to enable and disable the converter. When enabled, the MCP1642B/D will regulate the output voltage; when disabled, the MCP1642B/D will disconnect the path from input to output for “true-disconnect”. 1.4 WHAT THE MCP1642B/D TWO-CELLS TO USB POWER EVALUATION BOARD CONTAINS This MCP1642B/D Two-Cells to USB Power Evaluation Board kit includes: • MCP1642B/D Two-Cells to USB Power Evaluation Board (ADM00556) • Important Information Sheet DS50002231A-page 12 2014 Microchip Technology Inc. MCP1642B/D TWO-CELL TO USB POWER EVALUATION BOARD USER’S GUIDE Chapter 2. Installation and Operation 2.1 INTRODUCTION The MCP1642B/D has been developed for applications that require higher output current capabilities (see Figure 2-1) and low output ripple. It is a compact, synchronous, fixed-frequency step-up DC-DC converter. The regulated output voltage (VOUT) should be greater than the input voltage (VIN). Another important feature is that the device integrates the compensation and protection circuitry, such that the final solution requires a minimum number of additional components. The device can be disabled using the EN switch. The true disconnect option, MCP1642B/D, removes the normal boost topology path from input to output. 1000 VOUT = 5.0V IOUT (mA) 800 600 400 TA = 25°C 200 0 1.8 FIGURE 2-1: Supply. 2014 Microchip Technology Inc. 2.2 2.6 VIN (V) 3 3.4 MCP1642B/D - 5.0 VOUT Maximum IOUT vs. VIN Using Power DS50002231A-page 13 MCP1642B/D Two-Cell to USB Power Evaluation Board User’s Guide 2.1.1 Battery Considerations When considering a power solution for a design, the battery needs to be carefully selected. Alkaline batteries are a commonly available option that deliver good performance in a variety of applications. Energizer® Ultimate Lithium batteries are an alternative power solution that provides superior performance high drains and allows designers to utilize the full power range of the MCP1642B/D without sacrificing size or runtime. Energizer Ultimate Lithium batteries utilize a primary cell chemistry that contains higher energy than alkaline batteries, and has much better high-drain performance. Ultimate Lithium batteries produce a high, flat voltage profile that enables them to provide a high -energy capacity even at high drains. Additionally, Ultimate Lithium batteries have a very low internal resistance, allowing them to maintain a high voltage at very high loads. 28.7 Service Estimate (hours) 30.0 ® AA Energizer® MAX® AA Energizer® Max ® Energizer® Ultimate LithiumAA AA Energizer Ultimate Lithium 25.0 20.0 15.0 12.7 10.0 5.8 5.0 1.8 0.0 50 mA 250 mA 0.3 2.3 500 mA Constant Output Current with 5V DC VOUT Note: Service estimates apply to using two Energizer MAX AA or Energizer Ultimate Lithium AA batteries as the power source. Note that, if PG or feedback divider network is used, some additional input drain current should be included, but there will be negligible effects on the service estimates at these three load currents.

DS50002231A-page 15 MCP1642B/D Two-Cell to USB Power Evaluation Board User’s Guide 2.2 GETTING STARTED The MCP1642B/D Two-Cells to USB Power Evaluation Board is fully assembled and tested to evaluate and demonstrate the MCP1642B/D Switching Boost Regulator in a real world application. For in-depth evaluation, this board requires the use of external laboratory supplies and load. 2.2.1 Power Input and Output Connection 2.2.1.1 POWERING MCP1642B/D TWO-CELLS TO USB POWER EVALUATION BOARD Two AA battery holder and soldered test points are available for input voltage connections. The maximum input voltage should not exceed 5.5V. The output voltage will not remain in regulation for input voltages that are greater than or equal to the output voltage. The MCP1642B/D Two-Cells to USB Power Evaluation Board was designed to be used in the evaluation of the device. The package selected is MSOP-8. USB A connector or soldered test points are available to connect a load. The switch peak current limit will provide a safe maximum current value. The maximum output current for the converter will vary with input and output voltages; refer to Figure 2-1 or the MCP1642B/D data sheet for more information on the maximum output current. 2.2.1.2 BOARD POWER-UP PROCEDURE: 2. Connect input supply as shown in Figure 2-4 or connect two AA batteries in the battery holder on the bottom side of the board. 3. Connect system load to VOUT and GND terminals; maximum load varies with input and output voltage; see the MCP1642B/D data sheet for more information on the maximum load. Typically, the MCP1642B/D can supply a 5V output with 700 mA from a 2.8V input source at room temperature. Connect the (+) side of the load to VOUT and the negative (-) load to ground (GND). 4. Turn the device ON/OFF using the EN switch. 5. When EN is ON or high, the converter is enabled, the Power Good Indicator PG LED is turned ON and VOUT can be measured on the VOUT and GND terminals. When EN is low, the converter is disabled, the PG indicator turns OFF, and VOUT is floating and is disconnected from the input. Additional test points are available to visualize different signals (SW, PG, EN). The MCP1642B/D Two-Cells to USB Power Evaluation Board is also equipped with a USB A connector at the output. Using a USB B - micro/mini USB cable, the board can be connected to portable electronic devices and used as an alternative power supply when needed.

Installation and Operation 2.2.1.3 ADJUSTABLE VOUT SETTING The board comes with the fixed output value MCP1642B/D-50 option (VOUT internally set to 5.0V). If a different output voltage is desired, the MCP1642B/D-ADJ adjustable option can be used. In this case, the resistor divider consisting of RT and RB is used to set the converter output voltage. The value of the resistors can be calculated using Equation 2-1. EQUATION 2-1: VOUT R T = R B ------------- – 1 V FB Where: VFB = 1.21V for MCP1642B/D-ADJ 2014 Microchip Technology Inc.
