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.
The XC9131 series are synchronous step‑up DC/DC converters that integrate a 0.2 A N‑channel driver transistor and a 0.22 A P‑channel switching transistor. They can start from as low as 0.9 V input to generate a 3.3 V output, making them suitable for battery‑powered mobile equipment.
The device offers features such as load‑disconnection, auto‑discharge, UVLO protection, thermal shutdown, and soft‑start. It is supplied in a USP‑10B package, operates from –40 °C to +85 °C, and complies with RoHS and Pb‑free requirements.
Yes, a load‑disconnection function cuts the current path during shutdown.
