DC-DC converters are a type of electrical power source that converts power from one form to another. The REC3-1205SRW/H2/A/SMD-R is a module designed to convert direct current (DC) voltages to regulated and adjustable voltages, as well as provide input overload protection.

The REC3-1205SRW/H2/A/SMD-R is a step-down dc-dc converter, with a fixed input voltage of 12V and an adjustable output voltage from 0.98V to 8V. This converter is commonly used in devices such as laptops and tablets to provide various regulated output voltages. It has an efficiency of up to 94% and is able to deliver up to 2 Amps of current, depending on the output voltage selected.

The REC3-1205SRW/H2/A/SMD-R uses a switch-mode power supply (SMPS) design, which uses power switches and other components to quickly and efficiently transfer energy from one circuit to another. This type of topology can be used in isolated or non-isolated applications.

In isolated applications, a transformer is used to transfer energy between the input and output circuits of the converter. The transformer isolates the input and output circuits, which helps reduce electrical noise from the input circuit interfering with the output circuit. The REC3-1205SRW/H2/A/SMD-R has a built-in isolation transformer, so it can be used in both isolated and non-isolated applications.

In both types of applications, the converter works by varying the duty cycle of the power switches in order to regulate the output voltage. In non-isolated applications, the duty cycle is determined by a feedback loop, where an error-amplifier compares the output voltage to a reference voltage. The output voltage can be further adjusted by setting the feedback voltage through a control pin.

The REC3-1205SRW/H2/A/SMD-R also incorporates current and thermal protection features to help ensure the converter is safely used and operated. The current protection limits the output current drawn from the converter, while the thermal protection will shut down the converter if the temperature exceeds the threshold.

The REC3-1205SRW/H2/A/SMD-R is an efficient and reliable way to convert direct current voltages to regulated and adjustable voltages. It is well-suited for use in devices such as laptops and tablets and is designed to operate safely and reliably in both isolated and non-isolated applications.
