XCL105B331H2-G

XCL105B331H2-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. The device is able to start operation from an input voltage of 0.9V, suitable for equipment using a single alkaline battery or nickel metal hydride battery. The device able to allows the drive of subsequent devices by the bypass function which maintain continuity between the input and output. Applications include portable equipment, beauty and health equipment, wearable devices, game, hobby, PC peripherals, devices with 1~3 alkaline, 1~3 nickel hydride, 1 lithium and 1 li-ion.
