Denser and more efficient power supplies with lower vampire power are in ever-increasing demand. New technologies push back earlier limits while lowering cost. Demand Pulse Regulation (DPR), an emerging topology, offers both simplicity and efficiency. DPR can also provide an order of magnitude lower vampire current when combined with new triggered pulse generation circuitry.
That simple trigger circuit has other applications for IoT power and standby supplies, as well as for battery powered devices. The triggered pulse generation circuit will also be shown serving as an ultra-efficient power switch driver for a buck converter that runs on vanishingly low vampire power.
