Output Disconnect Shutdown option, works attached to a microcontroller application.</p> <p>This board demonstrates how to optimize battery life using the MCP1640, and an 8-bit low cost PIC microcontroller, to reduce the No Load Input Current for applications that operate in Standby mode for a long period of time. During Standby, the enable signal for the MCP1640 has a low frequency, with less than 1% positive duty cycle. This maintains the output of the MCP1640 device up to 2.3V, which is sufficient to keep the PIC microcontroller live. This solution reduces up to 80% of the No Load Input Current the MCP1640 consumes in PFM Mode.</p> <p>The MCP1640 device is a compact, high-efficiency, fixed frequency, step-up DC-DC converter. It provides an easy-to-use power supply solution, with a minimum number of external components.</p> <p><strong>Key Applications:</strong> One, Two and Three Cell Alkaline and NiMH/NiCd Portable Products, Single Cell Li-Ion to 5V Converters, Li Coin Cell Powered Devices, Personal Medical Products, Wireless Sensors, Handheld Instruments, GPS Receivers, Bluetooth Headsets, +3.3V to +5.0V Distributed Power Supply</p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul id="ctl00_ctl00_PageContent_SubPageContent_dtFeaturesText" class="prepend-top"> <li>Input voltage: one AAAA Alkaline battery</li> <li>Output voltage: 3.3V</li> <li>Output current: &lt; 130 mA</li> <li>Up to 75% efficiency</li> <li>Standby battery current: 14.5 &mu;A @ 1.5V input</li> <li>Start-up voltage: 0.65V at VIN = 1.2V, VOUT = 3.3V and IOUT = 1 mA, resistive load</li> <li>Automatic PFM/PWM operation</li> <li>PWM Switching Frequency = 500 kHz</li> <li>ON/OFF switch button, with 25 seconds ON</li> <li>LED status indication (Output ON and Low Battery)</li> <li>Energizer&reg; Battery Holder with reverse battery protection</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>MCP1640 Single Quadruple-A Battery Boost Converter Reference Design Board</li> <li>Important Information Sheet</li> </ul> <div id="devtool-required-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Required Tools</h3> <div id="devtool-required-devtools-content"></div> </div> <div id="devtool-accessory-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Accessory Tools</h3> <div id="devtool-accessory-devtools-content"></div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Documents</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Application Note</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/AppNotes/01337A.pdf" target="_blank">AN1337 - Optimizing Battery Life in DC Boost Converters Using MCP1640 (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Data Sheet</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/22234B.pdf" target="_blank">MCP1640/B/C/D Data Sheet (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Solution Guide</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/50001894C.pdf" target="_blank">Quick Guide to Microchip Development Tools (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">User Manual/Guide</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/51922B.pdf" target="_blank">MCP1640 Single Quadruple-A Battery Boost Converter Reference Design (pdf)</a> </div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Downloads</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Design Package</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/00318-R10.zip" target="_blank">MCP1640 Quad A Reference Design Firmware (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Schematics/Layout Files</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/105-00318-R1%20Gerbers.zip" target="_blank">MCP1640 Quad A Reference Design Gerbers (zip)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: microchip, power_management, stepup_boost_regulator, analog_demo_boards, MCP1640</div>
