DC DC Converters

A DC-DC converter, often referred to as a buck-boost converter, is an electronic power supply that converts a direct current of one voltage into another. It is one of the most common types of power converters available, commonly used in industrial, automotive, and consumer electronics applications such as laptop computer adapters and portable chargers. The design of a conventional DC-DC converter is relatively simple, consisting of two semiconductor switches and a transformer.

The SQ24T04120-PCB0 is an efficient, economical, robust DC-DC buck-boost converter. This device operates off a wide input voltage range of 4.5V-32V and provides a regulated output voltage of 0V-24V. The SQ24T04120-PCB0 provides a constant current output up to 6A with a switchover frequency of up to 400kHz, enabling high-efficiency power supply designs over the full temperature range.

The SQ24T04120-PCB0 is ideal for applications such as battery back-up systems, industrial equipment, communication systems, medical devices, LED driver, automotive, etc. It can be used in multi-output power converters and is highly configurable in terms of features such as voltage accuracy, transient response, output ripple, and efficiency.

The working principle of the SQ24T04120-PCB0 is based on the venerable buck-boost principals, which comprises two transistors operating in buck and boost mode to form a voltage buck-boost topology. Using Pulse Width Modulation ( PWM ) various output voltages and currents can be achieved, resulting in the transformer providing an output voltage as required.

The SQ24T04120-PCB0 features a built-in active voltage and current loop control circuit, which helps keep the output voltage and current stable and responsive.
