XCL105A251H2-G

XCL105A251H2-G is a XCL105 series synchronous step-up DC/DC converter which integrates an inductor with a 0.17ohm Nch driver FET and a 0.23ohm synchronous Pch switching FET built-in. It is able to start operation from an input voltage of 0.9V, suitable for equipment using single Alkaline battery or Nickel metal hydride battery. During the devices enter stand-by mode, it prevents the application malfunction by CL discharge function which can quickly discharge the electric charge at the output capacitor (CL). Application includes portable equipment, beauty and health equipment, wearable devices, game and hobby, PC peripherals, devices with 1~3 alkaline, 1~3 nickel hydride, 1 lithium and 1 Li-ion.
