The UC3573DG4 DC-DC switching controller is a Pulse Width Modulation (PWM) integrated circuit designed for switching regulation applications requiring low parts Count and minimum external components. The device features include: short-circuit protection, adjustable under-voltage lockout, output voltage adjustability and temperature shutdown protection. It is a low-cost, low power consumption, and highly efficient DC-DC switching controller that provides accurate regulation and high output current stability.

The UC3573DG4 is specifically designed for wide input voltage operation and is available in a wide range of output voltages. It is widely used in automotive, industrial, communication, computer, and consumer applications. Its maximum output current ranges from 1A to 5A depending on the output voltage and the input voltage.

The UC3573DG4 offers a built-in soft start feature which eliminates the need for an external soft start capacitor. It also offers an adjustable output voltage and an adjustable frequency range from 100 Hz to 1kHz. The device can be set up for either synchronous or non-synchronous operation.

The UC3573DG4 uses a high speed PWM controller and some external components to regulate the output voltage. It features short-circuit protection and adjustable under-voltage lockout. The device also features over-temperature shutdown protection and long terminal-to-terminal on-resistance. The PWM controller regulates the output voltage by varying the duty cycle of the output pulse, thus providing precise voltage regulation.

The UC3573DG4 is ideal for wide input voltage applications including low-voltage automotive, industrial, communication, computer, and consumer applications. The device is capable of providing high accuracy and stability with minimal external components. The device offers adjustable under-voltage lockout, output voltage adjustability, temperature shutdown protection, and low on-resistance. The UC3573DG4 is available in a range of packages, and offers efficient and reliable operation.
