Power supply lets you escape wimpy single-digit outputs
By Bill Schweber -- EDN, September 2, 2004
IC supply-rail voltages may be dropping toward 1V, but many designs need supplies in the hundreds or even thousands of volts due to the physics of the application. To meet this need, four series of high-voltage dc/dc converters from V-Infinity provide resistor-adjustable output to 2000V dc, with MBTF of 400,000 hours (Picture). These modular units take a 5 or 12V supply and pro-vide a high-voltage output at power levels of 0.5 to 3.5W with regulation as tight as 0.01%. Prices for these supplies, which operate from –10 to +60°C, start at $70 (single units).
