SG3525 SMPS Circuit Diagram SHORT CIRCUIT, OVER CURRENT PROTECTION
The only drawback of the circuit is that there is no over current protection, but this problem is solved by adding a fuse to the + and – output, but the electronic protection is not bad. When the voltage is supplied, the integrated version cuts off, you can use the following modification for this work (not tested).
Or in simple we can say that: “Circuit only missing overcurrent protection does not have, though the + and – output fuse adding solved this problem but electronically additional protection would not be bad sg3524 and sg3525 SMPS PWM control integrated short-circuit, over-current protection for the 10 numbered “shutdown” pin is used on this pin 5v Near No voltage is cutting the integrated version of the modification for this job, you can use the following (untested) shunt resistance should be done according to the current account to be drawn 0.6 / current.”
The SG3525A pulse width modulator control circuit offers improved performance and lower external parts count when implemented for controlling all types of switching power supplies. The on−chip +5.1 V reference is trimmed to 1% and the error amplifier has an input common−mode voltage range that includes the reference voltage, thus eliminating the need for external divider resistors. A sync input to the oscillator enables multiple units to be slaved or a single unit to be synchronized to an external system clock
