This voltage converter is compact and practical, greatly improving work efficiency.<br>2,Efficient Operating Modes:The boost converter module supports automatic PFM operating mode under light load and pass through mode under VIN>VOUT, meeting the needs of more applications.<br>3,Excellence Chip :This step up module uses excellent for TPS61023 chip, which has high thermal efficiency, compact size, and almost integrates all functions, including double 3A MOSFET switches.<br>4,Comprehensive Circuit Protection:This voltage regulator supports true disconnection of input and output during shutdown, with output overvoltage and thermal shutdown guard, and output short circuit guard.<br>5,Ideal for Battery-Powered Applications:When you need a large amount of 5V power supply, this boost module can come in handy and is very suitable for battery power projects with 2S or 3S batteries or a single Specifications:<br>Item Type: Boost Module<br>Input Voltage Range: 0.5V to 5.5V<br>Minimum Startup Input Voltage: 1.8V<br>MOSFET: Two 47 milliohm (LS), 68 milliohm (HS)<br>Maximum Switch Current Limit: 3.7A<br>Switching Frequency at VIN > 1.5V: 1MHz, VIN < 1V: 0.5MHz<br>Typical Shutdown Current for Vin and SW: 0.1uA<br>Reference Voltage Accuracy within -40-125℃: ±2.5%<br>Operating Mode: Automatic PFM operating mode under light load; Direct mode when VIN>VOUT<br>Protection: Output overvoltage and thermal shutdown protection; Output short circuit protection; When shutting down, the input and output are truly disconnected<br>Product size: 17.8 x 11.3 x 5.6 mm(0.70 x 0.44 x 0.22 in)<br>Color: Black<br><br>This boost module uses very small but highly efficient for TPS61023 chip. The chip integrates almost all functions, including dual 3A MOSFET switches. Please note that the switch will not tell you the maximum output, refer to the below!<br>We have set the feedback resistor to provide a 5.2V output, slightly higher than 5V, which helps to address voltage drop across cables. We have measured input and output currents and maximum consumption with desktop power supplies and electronic loads:<br>300mA maximum current output at 5V when input is 2V DC (minimum input voltage for start boost module)<br>500mA maximum current output at 5V when input is 2.5V DC (2 NiMH rechargeable batteries)<br>800mA maximum current output at 5V when input is 3V DC (2 alkalines batteries or a close to depleted LiPo)<br>1100mA maximum current output at 5V when input is 3.5V DC (polymer lithium nominal voltage)<br>1400mA maximum current output at 5V when input is 4V DC (3 NiMH, or new polymer lithium)<br>Most people will want to use LiPo or Li ion battery with a nominal voltage of 3.7V. Here is the efficiency at this voltage:<br>5.2V 100mA output requires 3.7V 160mA input (88%)<br>5.2V 250mA output requires 3.7V 400mA input (88%)<br>5.2V 500mA output requires 3.7V 800mA input (88%)<br>5.2V 1000mA output requires 3.7V 1800mA input (78%)<br>As you can see, when the lower current is about 500mA or lower, buzz will up about 88%. You can get 1A, but efficiency will drop a bit to 78%.<br>You will get a fully assembled splitter containing the TPS61023 and components and a small number of terminal connectors. 3-5V voltage is provided on the IN and ground pins. Then the OUT pin will have a 5V voltage. The enable pin can be pulled down to disable the output, which is a real disconnect, so the output will be completely powered off.<br><br>Package List:<br>1 x Boost Module<br>1 x Pin Header<br><br>Note:<br>1.
