XC9131 series is Discontinued. XC9131 Series ETR04012-011 1A Driver Transistor Built-In, Multi Functional Step-Up DC/DC Converters ■GENERAL DESCRIPTION ☆GreenOperation Compatible XC9131 series are synchronous step-up DC/DC converters with a 0.2Ω(TYP.) N-channel driver transistor and a 0.2Ω(TYP.) synchronous P-channel switching transistor built-in. A highly efficient and stable current can be supplied up to 1.0A 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 33Ωload resistor, suitable for mobile equipment using only one Alkaline battery or one Nickel metal hydride battery.
