9V Step-Up Voltage Regulator U3V40F9 SF_Hubs/Clamps which can output up toThis compact (0. 60. 6) switching step up (or boost) voltage regulator efficiently generates 9 V from input voltages as low as 1. 3 V and handles continuous input currents up to 3. 5 A. ( Note: minimum start up voltage is 2. 7 V, but it operates down to 1. 3 V after that.) The pins have a 0. 1 spacing, making this board compatible with standard solderless breadboards and perfboards. Overview The U3V40Fx family of boost (step up) voltage regulators are
