Application Field

The REC10-1205SRW/H2/A/M/SMD-R is designed for use in various applications where the input voltage needs to be converted from 5V to 12V DC. It can be used for providing auxiliary power in automotive, industrial, and medical systems, as well as in signal conditioning, intervalometers and other equipment. In addition, this device is suitable for a wide variety of battery powered applications such as tablet PC, laptops and embedded systems.

The REC10-1205SRW/H2/A/M/SMD-R features high efficiency, up to 96%, low output ripple, wide operating temperature range from -40 to +85 °C and excellent load regulation.

Working Principle

The REC10-1205SRW/H2/A/M/SMD-R is a step-up converter that employs a synchronous rectification technique to achieve high efficiency and low EMI/RFI generation. The device consists of a main board, which contains the control circuit and the power switches, and an output board, which contains the output inductor and the rectifier diode. The power switches are usually P-channel MOSFETs.

The operation of the device uses the following steps:

1. The main controller starts the switching process with the main switch, switching it on and off to provide energy to the inductor.
2. The energy that is stored in the inductor flows to the input capacitor, which in turn stores it for later use.
3. The stored energy is then transferred to the output capacitor and the output diode.
4. The output capacitor provides the necessary energy for the output voltage.
5. The output diode rectifies the output voltage so that it is the desired shape, typically a constant DC voltage.
6. The voltage is then monitored by the controller, which regulates the output voltage by adjusting the duty cycle of the main switch.

The REC10-1205SRW/H2/A/M/SMD-R is a highly efficient and reliable DC-DC converter that can be used in a variety of applications. It has a wide input voltage range and an adjustable output voltage. It is also designed to have a low EMI/RFI generation and excellent load regulation. Additionally, the device is fully protected against over-voltage, over-temperature, and short-circuit conditions.
