DC/DC - Switching Regulator
MORNSUN DC DC switching regulator is the high efficiency non-isolated dcdc converter with the package of SIP, DIP, SMD or chassing mounting, and the efficiency is high up to 95%. The newest regulated output K78-R4 series released recently has undergone a fundamental change in dimension and packaging which manufactured via the chiplet SiP(system in package) process, and the appearance of R4 has changed from the simple and roughness to the refinement.
