Rec3-4815DRWZ Working Principle

Rec3-4815DRWZ/H/B/SMD-R presents a typical buck converter configuration to achieve voltage step-down from input to output.

A buck converter integrates a power switch, either MOSFETs-based PWM or an LDO linear regulator IC. With MOSFET-based on/off switch conversion control method, the Rec3-4815DRWZ/H/B/SMD-R uses an integrated REC controller with Pulse-FSK modulation. This scheme allows the controller to be synchronized with an existing clock with certain frequency reference.

When the power switch turns on, energy gets stored in the inductor and discharged to the output side after the switch turns off. The inductor connected between the input and output side serves two functions. It holds the stored energy, and filters the output ripple. By changing the switching frequency, the device can achieve its successful power conversion from DC to DC.

Conclusion

Rec3-4815DRWZ/H/B/SMD-Ris an ideal DC-DC buck converter designed for applications needing higher power output. With its high power density, low noise, and small size, it can provide accurate and efficient power conversion and conversion control for various power systems.
