i explained SG3525A / SG1525A / SG2525A Pulse Width Modulator Controller functional description, pinout, circuit diagram and test circuit
The SG3525A, SG3527A pulse width modulator control circuits offer
improved performance and lower external parts count when implemented for controlling all types of switching power supplies i,e. buck converter, forward converter, half bridge, full bridge, push pull, boost converter, buck boost converter, continuous or discontinuous mode flyback SMPS. its 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. A wide range of dead-time can be programmed by a single resistor connected between the CT and Discharge pins. These devices also feature built-in soft-start circuitry, requiring only an external timing capacitor. A shutdown pin controls both the soft-start circuitry and the output stages, providing instantaneous turn off through the PWM latch with pulsed shutdown, as well as soft-start recycle with longer shutdown commands. The under voltage lockout inhibits the outputs and the changing of the soft-start capacitor when VCC is below nominal. The output stages are totem-pole design capable of sinking and sourcing in excess of 200 mA. The output stage of the SG3525A features NOR logic resulting in a low output for an off-state while the SG3527A utilized OR logic which gives a
high output when off.
• 8.0 V to 35 V Operation (maximum 40vdc)
• 5.1 V ± 1.0% Trimmed Reference
• 100 Hz to 400 kHz Oscillator Range (maximum 500KHZ)
• Separate Oscillator Sync Pin
• Adjustable Deadtime Control
• Input Undervoltage Lockout
• Latching PWM to Prevent Multiple Pulses
• Pulse-by-Pulse Shutdown
• Dual Source/Sink Outputs: ±400 mA Peak

Walikum Salaam Janab Bhai Saab Have A nice Day
Mashallah Very Nice Sharing Bhai
Lovely video Haseeb.
You made learning it easy
Thank you so much for making the time to make this wonderful video! I have a powered speaker with a power supply that uses both this KA3525A as well as a VIPer22A. The data sheets both say they are used for SMPS. The VIPer22A is used on the primary side of the transformer, while the KA3525A is used on the secondary side of the transformer. Can you comment on why someone would use both of these? Thanks again!
best regards
viper22a is a standby power section. this section turns on directly, when plugged in
when we turn on power key or from remote, that time ka3525 turns on to deliver main power supply, required by amplifiers and other power consuming elements
@@HaseebElectronics thank you so much for the quick reply! All the best to you from California.
Thanks for this great information
As always great video 👍

thank you for your lecture its more useful
I want ask you how can convert dc voltage 300v to sine wave by use SG3525 ??
Do you think that you can put out a video on the UC1526/3526ADW? It is virtually the same chip with 2 extra pins for Is+ & Is-. The datasheets I've found, leave much to be desired as far as as true mains AC-DC converter application. All I can find are instructions on how to make DC-AC inverter designs, which if working with a 12V starting voltage, can be realized via BJT's.
Useful. Please make video for UC3846 also.
Thank you!
Nice vedio
good work
Thanks a lot
Thank you bro. For this great information I have a question when pin 1 give 0 ohm with gnd this meaning get problem
Very nice
informative but sir. this we can learn own, plz make practical video if you can. thanks

Hi there, i am having an 12v/220V inverter where the SG3525 AP is having 5,7v in the pin10 shutdown so the IC is not working. Where those 5,7v come from ? is it from the protection inverter circuit or it is a bad SG3525 that needs to be changed. Pins 13 and 15 are both linked to the same capacitor. Thanks
In india local inverter use 3524 ic
@@Sartajkhankhan-r5f Thanks.
can you please make a video about making a inverter 50hz - 60hz with sg3525 with feed back ?
much appreciated !
I am looking at a schematic for a PLx- 1602 amplifier… it has a sg3525an, in power supply
The + input is tied to the vref(5.1v)
The - is tied to PRI_LO
So it’s full on all the time ?????
waalaikumussalaam
A simple question...
This ic has 100Hz to 400KHz frequency.
How can get I 50Hz for inverter or UPS ?
Hello friend, i want to vary the duty cycle manually ,between 35% and the maximum,49%, with a trimpot i have the china board SG3525+LM358, how can i do that? this for fase 1 of a solar inverter from 25 vdc to 380 vdc; thank you
Can you tell me suitable resistors and capacitors for Rt, Ct, Dis to keep 30khz constant.🤔?

Please help me.
Bagaimana membuat duty cycle automatic,jika frekuensi naik,duty juga naik
Pls.can u make a video about ic ucc3570n
I have watch all the calculations videos and really understand, but you did not calculate the input pi filter(before transformer) and output lc filter, rectifier(after transformer) and full connection and calculation(practical) for the feedback using SG3525A , please can you help show us thanks.
these calculations are in process,
EMI / RFI filter. MOSFET selection, output rectifier, filter design calculations are in to be done
after completion of all calculations the full circuit will integrated and designed practically
@@HaseebElectronics thank you very much
The power of the machine was doubled to melt 7 mm, but in it it was cut by welding the aluminum, then the yellow and red light flashed and remained like this and did not weld with changing 6 to 9 pieces What is the solution

Hi sir, one of the PWM outputs of this SG3525A is higher in VPP than the other output. This can also be noticed after the secondary rectification as one of the square wave is taller than the next one. What can cause this issue?
good point
i am planning to prepare a practical video on sg3525 with each detail and problems and their solutions, it is expected in upcoming week
Plz sir we need it😍
I have the same microchip. If 1 leg rings on the 12th leg and the second leg rings on the 16th leg, the microcircuit is not working properly?
pin 16 is V Ref (5 volt Reference voltage) when we provide operating voltage to pin 15 & 13 then this pin number 16 must provide 5 volt DC regulated
pin 12 is ground pin
if we connect something to pin 16 and the chip doesn't work, it means that there is some short circuit is have something wrong. the ic must provide 5 volt regulated from its pin number 16.
by connecting some component, if this pin drops than 5 volt, the ic will not start, because this is basic requirement of the IC
@@HaseebElectronics thank you 😊
@@HaseebElectronics i don't have 5v on the 16pin, and my amplifier goes to defense
When I connect feedback to pin 1 and ground pin the IC just shutdown the dutycycle doesn't reduce my feedback voltage is 6.5v I connected the pin 2 to pin 16 please can you tell me why it shut's down when I connect the feedback
Hi, that's my problem too, it shuts down ,it does not decrease the Duty Cycle; tried lots of ways,and i cannot get it to reduce the Duty Cycle down from the 49%;
Does anyone know how to do it, imean, no theory please, someone who really has done it,and how? I think pin 9 MUST(?) be involved, i see that in all circuits; Thanks
