The Stability

In order to guarantee the stability working of internal circuit of switching power supply, an internal power supply circuit with stabilization output was designed in this paper. Based on the voltage stabilization principle of zener diode, the internal power supply circuit put the high input voltage into 5v output voltage. Because of using module circuit, the circuit structure is simplified effectively. Based on 0.35um BCD technology, the internal power supply circuit was built in PSPICE. According to the experimental result, the internal power supply circuit can output stably in different input voltage and environmental temperature.
