The SG3524 incorporates on a single monolithic chip all the function required for the construction of regulating power suppies inverters or switching regulators. They can also be used as the control element for high power-output applications. The SG3524 family was designed for switching regu- lators of either polarity, transformer-coupled dc- to-dc converters, transformerless voltage dou- blers and polarity converter applications employing fixed-frequency, pulse-width modula- tion techniques. The dual alternating outputs al- lows either single-ended or push-pull applications.

The SG3524 IC chips is a fixed frequency PWM (Pulse Width Modulation) voltage regulator control circuit, with indifferent outputs for single ended or push pull applications. The SG3524 IC integrated circuit has all the functions necessary for the production of a regulating power supply, electrical inverter or switching regulator on a single chip.Moreover it can be used as the control element for high power output purposes. We know pulse width modulation PWM theory, i.e. a method of adjusting the width of the pulses in a pulse train relative to a control signal. If greater the control voltage, wider is the resultant pulses. Using a sinusoidal frequency as the control voltage for pulse width modulator circuits, it is likely to generate a high power waveform whose average voltage varies with the sine wave, which is suitable for driving ac loads.

  • Regulating power supply.
  • Electrical inverter or switching regulator on a single chip.
  • Transformer-coupled dc-to-dc converters.
  • Transformer less voltage doublers, and polarity-converter applications employing fixed-frequency, pulse-width modulation (PWM) techniques.
  • The complementary output allows either single-ended or push-pull application. Each device includes an on-chip regulator, error amplifier, programmable oscillator, pulse-steering flip-flop, two uncommitted pass transistors, a high-gain comparator, current-limiting and shutdown circuitry.
