Description
When voltage in a circuit or part of a circuit raise above the designed limit, this is called overvoltage. Overvoltage can be dangerous depending upon the duration and magnitude of the overvoltage. Electrical and electronics devices are designed to operate at certain voltage, considerable damage can occur to the devices/ circuits in case of overvoltage. In order to avoid damage to the devices or circuit overvoltage protection devices must be employed in the circuit to avoid any unwanted condition.
IC AN8090 enables high speed control up to 500 MHz and has various protective function including overvoltage protection, overcurrent and thermal protection in order to improve the reliability of the power supply. IC is capable of directly driving the high power MOSFETs.

IC Electrical Characteristics/ Specifications
This device can be mounted on printed circuit boards in surface mount orientation, other electrical parameters of the device are given below
Working Principle
Block diagram of IC AN8090 is shown in figure above. It consists of multiple building blocks including timers, oscillators, latches, comparators, clock, and pulse width modulator circuits. IC provides two channel overcurrent protection, both on the negative side and positive side an intermittent operating function as protection when an over current state advanced further. Overheat and overprotection functions are also provided. Remote operating feature is also provided in the IC a HIGH signal to this pin will turn the IC OFF. Output is provided at the terminal two of the IC to drive any further load or transistor
Applications
IC AN8090 is used in the following applications
● Flyback applications
● Feed forward applications
Flyback Application
a fly back circuit using AN8090 is shown in figure below, Flyback converter is a buck boost converter with inductor split to form a transformer. When driving for example a plasma lamp or a voltage multiplier the rectifying diode of the boost converter is left out and the device is called a flyback transformer.
Feedforward Application
Feed forward system is a control system that passes control signals from one environment to the loads in another environment, circuit diagram of feedforward circuit using AN8090 is shown below
