Abstract :
The dynamic behavior and the operating range of a single-switch dual-output DC-DC converter is presented. The circuit is developed for automotive applications requiring regulated 12 V and 5 V supplies from a 24 V battery. The converter provides two independently regulated DC outputs from a single DC voltage source using one power semiconductor switch. Two discrete closed-loop feedback paths regulate the output voltages. One output voltage, supplied from a low-pass filter, is regulated by adjusting the duty cycle, while the other output, supplied from a higher-frequency bandpass filter, is controlled by the switching frequency. The converter is implemented using a 16-b Intel 8096 microcontroller communicating to external switching elements and control logic
