SG3525 Pulse width modulation controller IC

output of sg3525

Control-Integrated circuit for SMPS SG3525: Pulse frequency modulation and pulse width modulation are two types of techniques used in control integrated circuits for switch-mode power supplies. In Pulse frequency modulation technique on time of pulse remains constant but the frequency increases with the increase in load. But the Pulse frequency modulation technique causes some issues … Read more

How to use TL494 pulse width modulation control IC

PWM generation using TL494

TL494 is a PWM controller IC used for power electronics circuits. It comprises of on-chip two error amplifiers an oscillator with adjustable frequency feature, an output flip-flop having pulse steering control, and an output control circuit with feedback.  The error amplifiers can compensate voltage from –0.3 to VCC – 2 volts in common voltage configuration. … Read more
