DC-DC converters are an important class of switching power supplies that are widely used for data communication and mobile communication equipment, as well as many industrial automation and other control applications. The SQ24T08060-PBA0G is one type of DC-DC converter that is specifically designed for high-reliability applications. This article will discuss the application field and working principle of this particular DC-DC converter.

The SQ24T08060-PBA0G is a non-isolated, synchronous DC-DC converter that is designed for use in a variety of applications. It has a wide range of input voltages - from 4.5V to 48V - and provides a regulated output voltage of 6V with an output current of up to 25A. The device is complete with all necessary safety features, including short-circuit protection with hiccup mode and over-temperature control.

The SQ24T08060-PBA0G is suitable for a variety of industrial applications, such as drives, industrial automation, communications, metering, and medical equipment. It is also well-suited for LED lighting applications, power supplies, and battery charging in renewable energy systems.

The device is based on a two-switch synchronous buck regulator circuit with current-mode control and the average current-mode control (ACMC) technique. The ACMC technique helps to improve the peak-current capability of the device, as well as to reduce the amount of output ripple voltage. The ACMC technique works by adjusting the delay period between switching cycles, allowing the device to handle high peak currents that are not possible with traditional current-mode control regulators.

The SQ24T08060-PBA0G has a wide range of protection features, including over-current protection, over-temperature protection, short circuit protection, open loop protection, and under-voltage lockout protection. In addition, the device has an input reverse polarity protection that helps to prevent damage from incorrect wiring.

In order to maximize efficiency, the device features an active current-doubler circuit that enables it to support a wide range of operating frequencies from 100kHz to 2.2MHz. The device also features peak current mode operation to extend the device lifespan and reduce the amount of external components required.

In summary, the SQ24T08060-PBA0G is a high-performance, non-isolated synchronous DC-DC converter that is suitable for a wide range of applications. It has a wide input voltage range, a highly efficient active current-doubler, and a range of protection features. It is also capable of operating at frequencies of up to 2.2MHz, making it an ideal choice for high-reliability applications.
