DC/DC converters are widely used as a power supply in industrial applications. DC/DC converters are also used in battery-operated apparatus, such as laptop computers, where they provide a low standby power solution. REC5-1212SRW/H4/A converters are a type of DC/DC converter featuring wide input voltage range, high efficiency and high reliability.

The REC5-1212SRW/H4/A DC/DC converter is designed for industrial applications such as industrial control systems, server farms, power supplies, and other applications. It is capable of handling operating temperatures of -40 to +85°C and has two 25.2mm×25.2mm mounting holes to accommodate a variety of mounting requirements.

The REC5-1212SRW/H4/A DC/DC converter is a high-efficiency, isolated step-down converter, capable of producing an adjustable output voltage from nominal 1.2 V to 12 Vdc at a maximum current of 1.5 A. It operates from a 9 to 36 Vdc input voltage range and is internally protected from over-voltage, over-temperature and overload. In addition to excellent efficiency, the REC5-1212SRW/H4/A DC/DC converter offers wide Vin, fast transient response and low standby current.

Working Principle

The REC5-1212SRW/H4/A DC/DC converter employs a synchronous rectifier approach which provides high efficiency, low ripple and low noise. The switching frequency of the REC5-1212SRW/H4/A DC/DC converter can be adjusted by changing the external resistor connected to the SYNC pin. To ensure data accuracy, the load is continuously sensed by comparing the output current with the set current limit threshold. If the output current is greater than the threshold, the pulse width modulation (PWM) duty cycle is decreased proportionally to control the output voltage.

The converter also features a power-good signal which indicates when the voltage is within the error band of a user-selected set-point. This feature allows the user to monitor the output voltage and take the necessary action if the voltage exceeds the set-point. In addition, the converter employs full-cycle short-circuit protection to ensure the safety of the load in the event of an overload.

The REC5-1212SRW/H4/A DC/DC converter is a highly reliable power supply solution for industrial applications. Its wide input voltage range, fast transient response and low standby current make it suitable for a variety of applications. In addition, the integrated power-good signal and full-cycle short-circuit protection ensure high levels of safety and reliability even under extreme conditions.
