TOREX XC9131 Series 1A Driver Transistor Built-In Multi Functional Step-Up DC/DC Converters Manual
Update: 30 September, 2023
XC9131 series is a synchronous step-up DC/DC converter 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. During the operation of a shutdown, the load disconnection function enables to cut the current conduction path from the input to the output. The series has 0.5V (±0.01V) reference voltage integrated and being able to set an output voltage with external components.
