Top 5 Power products in January
Summary
In recent years, power supplies for lighting and motors for pumps are required to be smaller as devices become more sophisticated – spurring the demand for compact MOSFETs that are essential for switching operations. Generally, however, it has been difficult to reduce the size of Super Junction MOSFETs while maintaining an optimal balance between high breakdown voltage and low ON resistance. In response, after reviewing the shape of the mounted chip, ROHM was able to develop 5 models in the SOT-223-3 package (6.50mm × 7.00mm × 1.66mm) – providing a smaller, lower profile form factor without compromising the performance of conventional products. Bear has developed an innovative isolation technique that yields leakage current of less than 5 µA, exceeding the requirements for Type CF-rated medical devices. High efficiency up to 87% and high-grade components allow the converters to perform reliably over an ambient temperature range of –40°C to +95°C (with de-rating >55°C).
