This paper on the popular single-chip switching power supply chips for the multi-output DC voltage regulator and switching power supply design that started production. The choice of switching power supply a total of three major integrated circuits - MC68HC908QT2CD, UC3906, UC3842. UC3842 use of the PWM duty cycle technology control switch to adjust the output voltage, so as to achieve the objective of stability in output, UC3906 to use a floating battery charging and control through MC68HC908QT2CD by the main power switch and battery and circuit protection. The switching power supply system has multiple functions and DC output by the main function, and can automatically switch on the automatic protection system, alarm.
The completion of the main design elements include:
Based on auto ⑴ UC3906 to the battery charging circuit part of the design;
⑵ design and to MC68HC908QT2CD as the core of the SCM control and protection circuit;
Automatic ⑶ the main electrical swi
