Other applications include high-end power supplies, UPS and industrial systems, and renewable energy applications.

Working Principle

The RM-1509S/HP operates by using a buck topology, consisting of input filtering, a main switch, an inductor, and an output rectifier. With this configuration, the incoming input voltage is filtered, and then adjusted by the main switch. The high-side switch then supplies the energy to the inductor, and the inductor stores the energy temporarily during the time between switching cycles. During the cycle, a low-side switch controls the current and the voltage across the inductor, which determines the output voltage. The current then flows through the output rectifier, which then feeds into the output. This process is then repeated constantly with each switching cycle. This DC-DC converter provides exceptional power conversion efficiency, allowing higher power densities in a small form factor. With its efficient operation, the RM-1509S/HP produces less heat, reducing heat dissipation and component costs. The soft switching design further enhances reliability and reduces power consumption.
