| Abstract: pulse width. The exact pulse width is modulated to regulate a converter's output voltage during , switch in low power applications. One example of this is a Flyback converter configured as shown in , (-7V max) with a +5V DC input. Higher voltage outputs, for example -12V to -15V, can be obtained by using a UC3843 with a higher maximum input voltage ( 30VDC 30VDC ). Here too there are some limitations. , design of the Flyback converter, and others. For further assistance contact a Unitrode Field Application ... | Original |
