Working Principle of R1DA-051515-R

R1DA-051515-R is a non-isolated buck (step-down) DC-DC converter, which is used to reduce the output voltage from a source and convert it into a regulated lower voltage. It consists of N-channel MOSFETs (metal-oxide semiconductor field-effect transistors) connected in the buck structure and a controller with cycle-by-cycle current limit and loop compensation.

In a buck converter, an input voltage is applied to a switch and the switch is closed at times to provide an output voltage. The output voltage is therefore lower than the input voltage. When the switch is closed, a current is allowed to pass, and when the switch is open, the current is blocked from passing. The controller keeps the current limited and controlled. It does this by constantly measuring the input voltage, output voltage, and current. When the current reaches to its maximum (which is set by the controller) it closes the switch to reduce or stop current flow. This is known as cycle-by-cycle current limiting. A capacitor is used to filter out any unwanted noise.

In addition to the current limiting, there is a loop compensation. It is designed to keep the system stable by providing a voltage reference waveform. This is done by using an error amplifier to compare the output voltage with the reference waveform, and then adjusting the on-time of the converter to keep the output voltage at the desired level. The system is continuously monitored and adjusted to keep it stable.
