The CD4093B consists of four Schmitt-trigger circuits. Each circuit functions as a 2-input NAND gate with Schmitt-trigger action on both inputs. The gate switches at different points for positive and ...
Figure 1 shows a flyback power supply that has low noise and uses a simple CMOS 4093 IC for its control. The electrical noise of a converter arises mainly when current switches on. Diode recovery and ...
