This board uses the MCP1650/51/52/53 in two high-power, boost-converter applications. The first application features the MCP1651 (8-pin MSOP) with the low battery detect feature. The input voltage for the MCP1651 application is 2.8V to 4.8V, with the output boosted to 5V. The second application uses the MCP1653 (10-pin MSOP), which features both the low battery detect and power good features. The input voltage for this application is 3.3V, with the output boosted to 12V. 1.3 WHAT THE MCP1650 BOOST CONTROLLER EVALUATION BOARD INCLUDES This MCP1650 Boost Controller Evaluation Board Kit includes: • The MCP1650 Boost Controller Evaluation Board • The MCP1650 Boost Controller Evaluation Board User’s Guide • The MCP1650/51/52/53 Data Sheet 2004 Microchip Technology Inc.

Installation and Operation 2.1 INTRODUCTION The MCP1650 Boost Controller Evaluation Board is designed to demonstrate Microchip’s family of high-frequency boost controllers. The product family consists of four high-frequency, boost-converter devices having different combinations of features. All devices in the family feature 750 kHz high-frequency, low quiescent current, shutdown capability and the MSOP package. The MCP1650 8-pin MSOP is the base device. The MCP1651 8-pin MSOP includes all of the features of the MCP1650, with the addition of a low battery detect and low battery output (LBO) indicator. The MCP1652 8-pin MSOP includes all of the features of the MCP1650, with the addition of a power good (PG) indicator. The PG indicator is an open-drain output that is high-impedance when the output voltage of the converter is within ±15% of its intended regulation range. When the output of the regulator is not within the ±15% range, the PG pin will sink up to 10 mA. The MCP1653 10-pin MSOP has all features; the LBO and PG, along with the base features of the MCP1650. 2.2 FEATURES The MCP1650 Boost Controller Evaluation Board has the following features: • Evaluation of the MCP1651 in a boost application configured in the Bootstrap mode. This application circuit will regulate the output to 5V while delivering 1A of current as the input voltage varies from 2.8V to 4.8V. • Evaluation of the MCP1653 in a boost application configured in the non-Bootstrap mode. This application circuit will regulate the output voltage to 12V while delivering 400 mA of output current as the input voltage varies from 3.0V to 3.6V. 2.3 GETTING STARTED The MCP1650 Boost Controller Evaluation Board is fully assembled and tested for evaluation and demonstration of the MCP1650 family of boost controllers. This board requires the use of external lab supplies and loads. Both application circuits have a fuse for input overcurrent protection. As with all boost converters, there is a path from VIN to VOUT through the boost inductor and output diode. In the case of a shorted output, there is no means of protecting the inductor and diode, so an external fuse is provided. MCP1651R Application Circuit 1. Powering the MCP1651 bootstrap application circuit: - Apply the input voltage to the surface-mount test points provided. The input voltage source should be limited to the 2.8V to 4.8V range to regulate the 5V output. The input voltage must not exceed the +5.5V maximum rating of the MCP165X. The source current necessary to regulate the output voltage to +5V at 1A should be approximately 3A. _ - Connect the positive side of the input source (+) to the +VIN 1 test point (TP1). Connect the negative, or return side, (-) of the input source to the _ GND test point (TP4) located next to +VIN 1. 2004 Microchip Technology Inc. DS51462A-page 5 MCP1650/1/2/3 Evaluation Board User’s Guide - The Under Voltage Lockout (UVLO) feature will prevent the MCP1651 from starting the converter until the input voltage is above the minimum threshold. Once the input voltage is raised above the UVLO threshold, the converter will begin to boost the output voltage up to 5V. The output voltage is fed back to the input so that, once the Boost converter has started, it can run down to lower input voltages at reduced load currents. 2. Applying the load to the MCP1651 bootstrap application circuit: - To apply a load to the MCP1651 application circuit, the positive side of the _ load (+) should be connected to the +VOUT 1 test point (TP2). The negative side of the load should be connected to the GND test point (TP3). The maximum load current should not exceed 1A while the input voltage is within the range specified for this application (2.8V to 4.8V). 3. Using the shutdown feature of the MCP1651 application circuit: - To shutdown the MCP1651, use a jumper wire to connect the SHDN test point (TP5) to the GND test point (TP4). By grounding the shutdown pin, the MCP1651 will enter the shutdown state and minimum quiescent current will be drawn from the input source. To resume normal operation, remove the jumper pin from the SHDN test point to ground and the MCP1651 will start. 4. Low Input Status LED: - The MCP1651 has a low input voltage status indicator that will provide visual indication (via a LED) when the input voltage is below 3V. This LED will illuminate to provide a warning that the input voltage is approaching the minimum 2.8V input voltage. MCP1653S Application Circuit 1. Powering the MCP1653 non-bootstrap application circuit: - Apply the input voltage to the surface-mount test points provided. The input voltage source should be limited to the 3.0V to 3.6V range to regulate the 12V output. The input voltage must not exceed the +5.5V maximum rating of the MCP165X. The source current necessary to regulate the output voltage to +12V at 0.4A should be a minimum of approximately 3A. - Connect the positive side of the input source (+) to the +VIN_2 test point (TP6). Connect the negative, or return side, (–) of the input source to the GND test point (TP8) located next to +VIN_2. - The UVLO feature will prevent the MCP1653 from starting the converter until the input voltage is above the minimum threshold. Once the input voltage is raised above the UVLO threshold, the converter will begin to boost the output voltage up to 12V. To maintain regulation of the 12V output, the input voltage range should be between 3.0V and 3.6V. 2. Applying the load to the MCP1653 non-bootstrap application circuit: - To apply a load to the MCP1653 application circuit, the positive side of the _ load (+) should be connected to the +VOUT 2 test point (TP7). The negative side of the load should be connected to the GND test point (TP10). The maximum load current should not exceed 0.4A while the input voltage is within the range specified for this application (3.0V to 3.6V). 3. Using the shutdown feature of the MC1653 application circuit: - To shutdown the MCP1653, use a jumper wire to connect the SHDN test point (TP9) to the GND test point (TP8). By grounding the shutdown pin, the MCP1653 will enter the shutdown state and minimum quiescent current will be drawn from the input source. To resume normal operation, remove the jumper pin from the SHDN test point to ground and the MCP1653 will start. DS51462A-page 6 2004 Microchip Technology Inc. Installation and Operation 4. Low Input Status LED: - The MCP1653 has a low input voltage status indicator that will provide visual indication (via a LED) when the input voltage is below 3V. This LED will illuminate to provide a warning when the input voltage is at the minimum 3.0V input voltage. 5. Power Good Status Indicator. - The MCP1653 has a power good status indicator that will provide a visual indication (via a LED) when the output voltage of the application circuit is more than ±15% out of regulation. D4 will illuminate to indicate that the output voltage is out of regulation. 2004 Microchip Technology Inc.
