Working Principle

The REM3-4805S/A is based on the low-voltage bidirectional buck-boost (LBBB) converter topology, using a synchronous rectifier for low dropout and low input-voltage operation. The converter comprises a fixed-frequency control IC and three high-voltage MOSFETs that produce a regulated output voltage from a wide input voltage range of 4.5V to 28V. This allows the converter to operate in both step-up and step-down configurations and be used in applications requiring both push-pull converter and flyback converter modes.

The switch-mode design of the REM3-4805S/A provides a high-efficiency solution that helps reduce energy losses while optimizing system performance. The converter also features an integrated voltage-mode control for stability and reliability, enabling quick response to load changes. These features are especially well-suited for load-sharing applications where synchronization between multiple converters is essential.

The bidirectional configuration ensures that the output voltage is regulated regardless of source voltage or direction of current flow, and the converter is further protected against short circuits, overload, and undervoltage conditions. The converter features soft-start and over-voltage protection functions to ensure safe system operation even under high-load conditions.

The REM3-4805S/A is a reliable, high-performance DC/DC converter that provides a wide input voltage range with high efficiency and excellent transient response. Its features make it ideal for applications requiring the reliable delivery of output power from both step-up and step-down configurations. It is well-suited for use in a variety of industries from automotive and medical to telecommunication and aerospace.
