UC3524ADWTR Integrated Circuits (ICs)

Introduction of UC3524ADWTR

UC3524ADWTR is a current-mode-controlled DC-DC switching controller that integrates various high-performance functions. It utilizes the commonly used topology of flyback converter, follows the standard voltage or current-mode control method, and can be both integrated or remotely programmed, making it widely applicable in various high-performance power regulating and controlling applications.

Applications Fields

The UC3524ADWTR is designed for a wide range of applications specializing in power management, such as step-down, step-up or flyback converters, adjustable voltage regulators, current drivings, motor controls, linear regulators and many more. This controller can support high-precision, high-efficiency, high-reliability as well as low power consumption.

Working Principle

The UC3524ADWTR works on current-mode control. It includes an oscillator and a comparator, both of which provide a direct interface to the standard control loop for complete compensation and synchronization. The precision control-loop controls the heartbeat of the oscillator, which in turn regulates the duty cycle. The comparator helps it to detect the load current and continuously adjusts the duty cycle according to the average voltage feedback.

The controller is capable of driving a power MOSFET switch directly, and provides requisite amount of base drive. Moreover, the various diagnostic outputs are provided to check the condition of the switch and to protect the system from overloads and overheating.
