Working Principle

The RPA20-2405SAW/P-HC is a synchronous step-down type converter. At the heart of the circuit is a high-frequency connection bridge transformer, made up of two pairs of windings. The input voltage is applied to the primary winding, which then induces an output voltage in the secondary winding.

When the primary winding current is constant, the output voltage is determined by the ratio of the number of turns in the primary to the number of turns in the secondary winding. This output voltage can be adjusted by changing the duty cycle of a control pulse that is fed to the primary winding.

The RPA20-2405SAW/P-HC also incorporates an advanced thermal management system, making it suitable for even the most demanding environments. It also includes integrated protection functions, such as output overvoltage protection and input under-voltage protection.
