Working Principle

The REC8-243.3SRW/H2/A/M/SMD operates on a fixed frequency PWM (Pulse Width Modulation) control system. It uses an integrated voltage detector to monitor the input and output voltages, and control the PWM duty cycle accordingly. The duty cycle of the PWM signal is adjusted to maintain the output voltage at the desired value despite variations in the input voltage. When the input voltage increases, the duty cycle is decreased and vice versa. This ensures that the output voltage remains constant, even when input voltage fluctuates. The output voltage is adjustable and can be programmed by applying a voltage to the external programmer pin. This allows the user to easily adjust the output voltage to suit different applications.

The REC8-243.3SRW/H2/A/M/SMD also incorporates protection features such as over-voltage protection, under-voltage protection, short-circuit protection, over-temperature protection, and over-current protection. These features ensure that the converter operates within its safe operating range, and prevent damage to components or system failures due to extreme conditions.

The REC8-243.3SRW/H2/A/M/SMD is a high-performance and reliable DC–DC converter that can be used in a wide variety of applications. With its adjustable output voltage and protection features, the REC8-243.3SRW/H2/A/M/SMD is an ideal choice for powering sensitive electronic components and providing reliable and efficient power conversion.
