Introduction
The UC2842N is a non-isolated type of DC DC switching controller designed by Texas Instruments Incorporated (TI) which is the world’s largest integrated device manufacturer and supplier of analog and embedded processing solutions. It is mainly used for power system designs such as in commercial and industrial applications, especially for solar and LED lighting systems.

Application Field
As mentioned before, the UC2842N are primarily created for use in solar and LED lighting systems, which are known for their wide range of power applications and requirements. This type of power controller is equipped with features such as a high frequency operation and an ultralow control current operation which is highly effective and efficient in power control, particularly in solar systems. However, the UC2842N can also be used in other applications such as in motor drives, lighting systems, computer peripherals, and in home appliances.

Working Principle
The UC2842N works mainly by using a pulse width modulation (PWM) system. Using the PWM system, the UC2842N will receive a signal from an external processor or dedicated hardware and convert it into a square wave signal with a certain frequency and amplitude that will be used to drive a switched mode power supply (SMPS) load. The converted signal will then be used by the SMPS to control the switching of the power supply’s input and output transistor such that the power output from the power supply will be regulated as desired and predetermined by the external processor or dedicated hardware. The UC2842N also has other features and capabilities such as short protection, low voltage lockout, overvoltage protection, and a programmable soft start to ensure the safety of the power system as well as its components.

Conclusion
The UC2842N is an efficient, reliable and cost-effective power controller which is suitable for a wide variety of different power applications. It is capable of receiving signals from an external processor or dedicated hardware and converting these signals into a square wave signal with a certain frequency and amplitude. This square wave signal will be used by an SMPS to control the switching of its input and output transistor for a regulated power output. Asides from this, the UC2842N also has other features and protections such as short protection, low voltage lockout, overvoltage protection, and a programmable soft start for maximum safety and stability of a power system.
