Combination of 555 timer and two NE550 voltage regulators provides voltage mu Itiplication along with regulation of independent DC outputs. Selected oscillator frequency of 17 kHz optimizes performance of transformer. Can be used to power opamps from either TTL supplies or 6-V batteries. Line and load regulationare 0.1 %, while power efficiency at full load of 100 mA is better than 75%.—R.Solomon and R. Broadway, DC-to-DC Converter Uses IC Timer, EDN Magazine, Sept. 5, 1973, p 87, 89, and 91.
