Ultra-High Efficiency DC/DC Converter Circuit
Converter block diagram – IP block within dotted line; separate blocks (purple) also available as stand-alone IP
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.

Ridgetop is certified as category 1A under the Defense Microelectronics Activity (DMEA) as part of the Trusted Supplier Program. Ridgetop has history of designing analog and mixed signal ICs for demanding applications in space satellites that are subjected to extreme temperatures and radiation. Our designs have utilized bulk CMOS, CMOS-SOI, and SiGe at process geometries down to 28 nm channel lengths. Radiation hardness is also a concern, and Ridgetop has addressed those requirements as well. A recent Ridgetop design was delivered to ON Semiconductor for the U.S. Air Force STELLAR Star Tracker.
Under contract to NASA, Ridgetop designed an effective 3-axis wireless rotational sensor. The RotoSense™ sensor has been tested on fast-spinning pinion gears on helicopter gear boxes, and also rolling stock for railroad safety improvements.
