5-Comparator IC Provides 3V-to-5V Regulator and µP Reset


摘要 : Using a multi-comparator circuit, a simple boost converter can be constructed to provide a higher output voltage as well as a reset circuit. This application shows how a 3V supply can produce an additional 5V output as well as a power-on-reset (POR) circuit. The application uses the voltage detector to produce an oscillator circuit that controls the external boost circuit and provide a regulated 5V output.
