Abstract: flyback uc3843 DN-43 Design Note Simple Techniques to Generate a Negative Voltage Bias Supply from a Positive Input Voltage by Bill Andreycak Developing a low power negative supply voltage from a positive input supply can be accomplished using some very common PWM control ICs. Typical applications include generating a negative five through twelve volt (-5V to -12V) supply for analog function ICs (OP amps), RS-232 communication circuits, and MOSFET or IGBT gate drives at power levels below a few Watts. Many PWM ICs

Abstract: three winding transformer DN-56A Design Note Single Switch Flyback Circuit Converts + 5 VDC to +/- 12 VDC for RS-232 and RS-422 Applications by Bill Andreycak Developing bipolar 12 volt supplies from a single +5 volt input can be accomplished using a number of conventional approaches. A boost converter is the most logical for the +12 volt output, however it cannot be used in some Interface circuit applications. One significant drawback of the boost topology is that even while off, the output voltage approaches the in
