microcontrollers, regulators for logic applications, and secondary power supplies.

The XC6230 series can also be used in consumer electronics, industrial equipment, communication modules, and electricity smart meters. In addition to a function that enables the output voltage and current limit value to be set externally and a function that prevents a reverse current higher than the input pin (VIN) from flowing into the output pin (VOUT), a rich variety of protective circuits such as overheating protection (TSD) and startup rush current prevention can be added.

The small USP-6C package (1.8 x 2.0 x h0.6mm) or SOP-8FD package (currently under development) can be selected as appropriate for the application. The output voltage and over-current limit value can be set using a total of only five chip capacitors and chip resistors, and as such these products make a significant contribution to space-saving design even while being multi-functional.

Another advantage of multi-functionality is the ability to set the customer’s desired output voltage and current limit value with only a single XC6230 series IC even when the power supply specifications vary by model. This enables standardization

of the IC and contributes to a reduction of cost and man-hours for design.In the future Torex will continue to employ its expertise in small-size and low-power consumption ICs to swiftly develop products that meet market needs and contribute to a richer and more abundant society.
