Linear-comparators are commonly used in AC to DC power converters, and their application fields range from energy efficient equipment to alternative energy systems. The TS3022IST is a linear-comparator designed to meet the high frequency performance requirements of AC to DC converters. This device provides high speed response and low noise operation.

This linear-comparator is a monolithic integrated circuit with low voltage operation and fast response times. It is suitable for controlling power converter circuits operating with input voltages up to 24V and output currents up to several amps. It also has a low power dissipation which makes it suitable for low power applications. With high frequency operation and low output noise, it is ideal for power supplies and AC to DC applications.

The TS3022IST features two inputs, one of which is a zero-cross detect (VZCD) input, and the other is an adjustable current limit (VADC) input. The VZCD input is used for detecting the zero-crossing point of an input AC waveform and to reset the output current limit. The VADC input provides an adjustable current limit to the output, independent of the input voltage. The VADC is adjustable from zero to twelve volts to suit different applications.

The TS3022IST has an internal temperature-compensated current-sense amplifier with a built-in temperature-sensing resistor. This temperature-compensated current-sense amplifier provides accurate current limiting. The current-sense resistor and external components of the linear-comparator are designed to provide excellent temperature compensation. The current-sense resistor also acts as a current-controlling element when the voltage of the VADC pin is adjusted.

The linear-comparator uses an opto-isolator to isolate the power electronics in the device from the mains power supply. It provides an effective level of protection against electromagnetic interference (EMI) and over-voltage. The opto-isolator also isolates the device in the event of a short circuit.

The TS3022IST has a wide operating temperature range from -40 to +85°C, making it suitable for use in a variety of applications. The device is also RoHS compliant, making it a cost-effective and reliable solution for AC to DC power supply applications.

The TS3022IST is conveniently packaged into a SOP8 package for easy mounting onto a PCB. It is a low-cost solution for control applications that require superior performance and fast response. With its low-voltage operation and excellent noise immunity, this device is suitable for a wide variety of power supply applications. Additionally, it provides an efficient and accurate current-sense amplifier, which makes it a great choice for power converter applications.
