The full power-supply range of NE555 extends from 4.5 to 16 V, but its use near the maximum supply value with the maximum specified current of 200 mA, and at high frequency, can be a problem. This file type includes high resolution graphics and schematics when applicable. (We will use only Schottky diodes, to reduce the voltage losses to the minimum.) Download this article in. Note that the results also depend on the specific manufacturer of these multisourced ICs and on the quality of the related components. However, another very popular IC, the LM386 audio amplifier, may be a better solution in this application. The bipolar NE555 timer IC is widely used in inductorless dc-dc converters, most frequently in doubling and inverting converters.
