I’ve shared a lot of SMPS power supply projects with IR2153, especially AT, ATX power supply. The IR2153 works great for evaluating power transformers. Even bigger companies such as Yamaha have used the 8 pin MOSFET driver integration in their products. an integrated but not very common use in DIY environment I did not have the chance to make a trial that we did not already have in our market …
According to the IR2153 integration, the greatest feature of the IR2161 is the built-in current sense short circuit protection system, the power MOSFET is protected against the current drawn through the low-ohmic shunt resistor connected to the source pace, unfortunately the working frequency can not be adjusted with external components, this has a working frequency of 70kHz. I think 34kHz … 70kHz)
General features of IR2161
• Smart half bridge driver
• Short Circuit Protection
• Overload Protection
• External Triggerable Closure
• Extreme Temperature Protection
• Frequency Modulation (for lower EMI)
• Low Power Starting
• phase cutting dimmable
• Output Voltage Change Compensation.
• Real Bottom Start
• Adaptive Dead Time

IR2161 Schaltnetzteil SMPS-Schaltung
Ich habe eine Menge von SMPS-Stromversorgungsprojekten mit IR2153, insbesondere Schaltnetzteil SMPS AT, ATX-Netzteil geteilt. Der IR2153 eignet sich hervorragend zur Bewertung von Leistungstransformatoren. Selbst größere Unternehmen wie Yamaha haben die 8-Pin-MOSFET-Treiberintegration in ihren Produkten eingesetzt. eine integrierte aber nicht sehr häufige Verwendung in DIY-Umgebung Ich hatte keine Chance, einen Versuch zu machen, den wir noch nicht in unserem Markt hatten …
Gemäß der Schaltnetzteil SMPS IR2153-Integration ist das größte Merkmal des IR2161 das eingebaute Current-Sense-Kurzschlussschutzsystem, der Leistungs-MOSFET ist gegen den Strom geschützt, der durch den niederohmigen Nebenschlusswiderstand gezogen wird, der mit der Quellengeschwindigkeit verbunden ist, leider die Arbeitsfrequenz kann nicht mit externen Komponenten eingestellt werden, dies hat eine Arbeitsfrequenz von 70 kHz. Ich denke 34kHz … 70kHz)

0-30V 10A Power Supply Circuit LM723 TIP3055
0-30V 0-10A laboratory type adjustable power supply I mentioned in the article of the relay bypass circuit for regulated power supplies, the K7200 kit version is 1/1 clone There is almost no difference except a few changes in PCB design and the use of 6 power transistors. LM723 amplifiers were used at the control level of the power supply circuit, and TIP3055 transistors were used at power level. Transformer 2X15V AC 300W
Do not forget to compare the schematic and pcb drawings before making the circuit. If the circuit does not have a very complicated structure, you can cancel the bypass circuit and make it even simpler. In this case you need to use stronger transistors and better cooling .. R30, R9 volt meter (icl7107) R10, R29 amps meter (icl7107) is used for measuring inputs. Since volt amperage measurement modules are popular in the market, you can use modules instead of icl7107 circuits, you do not need to use resistors in this case.
