The UC2833DWTR is also suitable for EMI protection from power supply noise, power line transients, and electromagnetic interference. Furthermore, it offers a wide range of features for power supply design, control, voltage conversion and monitoring.

Working Principle

The UC2833DWTR is a linear voltage regulator controller that is normally operated in a closed-loop high-power output mode in order to regulate a certain output voltage. Its primary objective is to provide an efficient, stable and reliable supply of power to the application. Its circuit block diagram and structural overview is as follows:

The UC2833DWTR works by regulating the output voltage set by external components. Typically, voltage control is achieved through the application of external resistors and capacitors. This is done by for example connecting two resistors, R1 and R2, between the output voltage and the reference voltage. The reference voltage is provided by the feedback voltage of the regulating loop, which is the voltage at the VOUT pin. The feedback value is then compared against the reference voltage, which is set by input to the PW pin. Currently, the UC2833DWTR can support up to two internal controls for setting output voltage. Once the difference between the reference voltage and the feedback voltage is detected, an error amplifier will then adjust the voltage at the PW pin to correct the error.

In addition, the UC2833DWTR also has a wide range of protection features to ensure the safe operation of the device. These features include over voltage protection (OVP), under voltage protection (UVP), over temperature protection (OTP) and short circuit protection (SCP). These protection measures will ensure that the operating conditions of the device are always within specification, as well as protect the device against short circuits, over temperature and other abnormal conditions.
