Working Principle

The working principle of RY-1505D/P is simple. It takes the incoming power through the four external pins and converts it into a desired output voltage through an internal switching device. The external caps hold the charge and deliver power to the output.

Input power enters the oscillator stage and is then amplified by the control IC. The output voltage is regulated by the integrated circuit and is set by the external resistor. The output voltage is then changed according to the input voltage by the turn-on/off times of the switching devices.

To further increase the output power level, the IC provides up to 10 pins for a synchronous rectifier to capture both the positive and negative cycles to deliver higher power efficiency. All the various functions are controlled and regulated by the IC.

RY-1505D/P can provide up to 82% efficiency and provides various protection features like output voltage monitoring, input fault protection, short circuit protection, and thermal shutdown. This DC DC converter is perfect for many applications and provides great performance.
