The UC2823QTR is a precision, current mode-controlled pulse width modulation (PWM) DC-DC switching controller. It is designed for use in a variety of applications including conversion of non-isolated supplies, such as battery-charged to regulated outputs, step up and down converters, as well as many other buck, boost and buck boost configurations. The UC2823QTR is a highly advanced, setting the parameters and operating correctly and is able to maintain steady state regulation even with significantly varying input and load conditions. It also has a built-in voltage supervision system with programmable under and over voltage limit thresholds.

This device\'s main application fields are in power supplies for such applications as CPU/ cooling fan speed control, solar inverter/LED driver and AC/DC buck/boost converters. The UC2823QTR engages when the input voltage drops or rises above the user-defined thresholds, providing a robust and efficient voltage regulation for the supply. It also has the capability to operate in a low-side PWM mode for controlling step up converters.

The UC2823QTR offers high precision and stability control, achieveing voltage accuracies 1% or better. It uses current mode control, which provides a fast and accurate response to load transients, keeping the output voltage closely regulated, while also carrying out all other standard PWM functions, such as pulse frequency direction control and over-current limiting. It also offers a high degree of programmability, allowing the user to customize regulation parameters to their application.

The UC2823QTR also comes with a variety of safety features to ensure complete safety and reliability. These features include an under voltage lockout and over voltage protection, as well as protection against over temperature conditions, output short circuit and over current. The device also offers programmable soft starts, allowing the power supply to start in a controlled and reasonable manner.

In summary, the UC2823QTR is a highly reliable and advanced current mode-controlled PWM DC-DC switching controller. It has many features, such as high precision and stability control, voltages accuracy of 1% or better and a wide range of safety features, making it ideal for use in many applications, particularly in power supplies for such applications as CPU/cooling fan speed control, solar inverter/LED driver, and AC/DC buck/boost converters.
