Introduction of DC DC Converters

DC-DC converters are devices that can convert DC electrical energy from one voltage to another. They are more efficient than traditional transformers, making them ideal for use in small spaces, such as portable electronic devices. The main components of a DC-DC converter include a power transistor, a switching regulator, a storage element for the energy, and a filter for smoothing the output voltage.

Application Field and Working Principle of PRD15-Q24-S5-N-M-TR

The PRD15-Q24-S5-N-M-TR DC-DC converter is a four-switch buck converter with a wide input voltage range of 4.5V to 18V and an adjustable output range of 0.5V to 12V. It has a built-in protection circuit to limit over-voltage, over-current, and over-temperature. The device also has built-in tracking and current-sharing functions to improve system performance.

The PRD15-Q24-S5-N-M-TR utilizes the buck converter topology, an efficient and reliable configuration able to deliver a constant output voltage from an input voltage that varies widely. The device uses a four-switch configuration, which allows it to regulate the output voltage accurately by controlling the duty cycle of the switching signals. The four switches are driven by a fixed-frequency PWM controller.

In order to provide maximum efficiency, the PWM controller switches between two different operation modes: continuous current mode and discontinuous current mode. In continuous current mode, current flows through the entire inductor even when the switches turn off, while in discontinuous current mode, current does not flow through the inductor and the output voltage is determined solely by the duty cycle of the switching signals.

The PRD15-Q24-S5-N-M-TR has current-sharing and tracking functions that allow multiple devices to work in parallel for higher current or higher power applications. The current-sharing feature allows all devices to share the total current equally, while the tracking feature allows them to synchronize their duty cycles.

In addition to the current-sharing and tracking functions, the PRD15-Q24-S5-N-M-TR also has various protection circuits including overvoltage protection, overcurrent protection, and overtemperature protection. The device is also equipped with an Enable pin for controlling its output voltage and a Soft Start pin for controlling its start-up speed.
