XC9141

XC9141/XC9142 Series ETR04018-003d Load Disconnection Function, 0.8A Step-up DC/DC Converters ☆Green Operation compatible ■GENERAL DESCRIPTION XC9141/XC9142 series are synchronous step-up DC/DC converters with a 0.3Ω N-channel driver transistor and a 0.3Ω synchronous P-channel switching transistor built-in. A highly efficient and stable current can be supplied up to 0.8A by reducing ON resistance of the built-in transistors. The series are able to start operation under the condition which has 0.9V input voltage to generate 3.3V output voltage with a 100Ω load resistor, suitable for mobile equipment using only one Alkaline battery or one Nickel metal hydride battery. The output voltage can be set from 1.8V to 5.5V (±2.0%) in steps of 0.1V. With the built-in oscillator, either 1.2MHz or 3.0MHz can be selected for suiting to your particular application. During the devices enter stand-by mode, A, D types prevent the application malfunction by CL Discharge Function which can quickly discharge the electric charge at the output capacitor (CL). B, E types is able to drive RTC etc. by Bypass Switch Function to maintain continuity between the input and output. C, F types is able to connect in output voltage OR circuit with other power supplies by Load Disconnection Function which breaks continuity between the input and output. ■APPLICATIONS ●Portable equipment ●Beauty & health equipment ●Wearable devices ●Game & Hobby ●PC Peripherals ●Devices with 1~3 Alkaline, 1~3 Nickel Hydride, 1...
