Have you ever installed a long cable run and found the voltage at the far end was too low to power the device? Or have you needed to power a *2V device and the only available power was *4V? Developed to provide a regulated *1V**6V DC output (adjustable), where voltage ranges from *0V to *6VDC, the TPS-BB**3 Buck Boost Converter is the answer. If voltage is either too high or too low at your equipment, the TPS-BB*3 can automatically boost (increase) or buck (decrease) voltage to meet the device's requirements. There is no effect on the output during the transition from buck to boost (or vica-versa). This module also features an on-board battery charging facility when the output is adjusted to *3.8V DC. Specifications & Features: * Input Voltage: *0 - *6V DC * Output Voltage: *4 V DC Nominal (*4 - *7.6V DC adjustable) * Output Current: 1 A Maximum * Dimensions: **4 mm W x *1 mm L x *8 mm H * Line powered * Onboard Battery Charger * Over current, short circuit & over temperature protection * Replaceable output fuse * Compact size & light weight * Extremely clean output (meets CISPR*2 Class B)
