The Ridgetop DC-DC switching converter/power supply design meets demanding requirements for size, efficiency, and voltage range, and greatly exceeds the performance of similar commercial products.

Combined with modern CMOS processing technology, ultra-small form factors can now be achieved, while maintaining high efficiency by use of small-area switching transistors. Built-in battery monitoring features allow the equipment in which it is deployed to determine the strength of the battery and predict when wear-out might occur. Using an on-chip digital-to-analog converter (DAC), we can take in a digital word and compare this voltage with the output voltage. Then we can modulate the output pass transistor that is used to set the output voltage. In this way, we can derive virtually any output voltage within the output range.

This DC/DC converter intellectual property is part of Ridgetop’s InstaCell™ library of analog/mixed signal design blocks.
