The MIC2174-1YMM-TR is a monolithic integrated circuit from Traco Power specifically designed for applications that require high current DCDC switching controllers, such as AC/DC power supplies, LED drivers and dc/dc converters.

The IC offers a wide range of protection features and advanced voltage regulation capabilities, making it ideal for high power applications. It is capable of regulating output voltages that range from 2.5V to 24V. The switching frequency of the IC is adjustable and can be set to any frequency between 200kHz and 1.2MHz.

At the heart of the IC is an internal pulse width modulated (PWM) controller, which is designed to provide constant voltage and current control of the system loads. The IC has an advanced current-mode control loop, which can detect and accurately regulate the output current precisely. This ensures that the system supply stays within the desired output limits and prevents over-current or under- voltage conditions.

The IC also includes an adjustable, user-programmable soft start feature, which helps to prevent large inrush currents during initial power-up. It also has a programmable dead-time control which allows for accurate current/voltage control and enhanced stability of the output voltage.

The IC has various protection features, such as over-voltage, over-current, short-circuit and thermal shutdown. The over-voltage protection prevents the overload of the system by limiting the output voltage to a safe level. The over-current protection protects the system from current overloads and short circuits, which could cause excessive heat and potentially damage the IC or the load connected to it.

The MIC2174-1YMM-TR is a highly reliable, efficient, and feature-rich DC-DC switching controller designed to provide solutions to a wide range of high power applications. It offers superior protection features, adjustable switching frequency, and precise voltage regulation, making it an ideal choice for high current applications.
