Mornsun

K78 Series Non-Isolated DC/DC Switching Regulator

Mornsun's regulator offers a wide input voltage range, smaller size, no heat sink, and is cost-effective

Image of Mornsun's Non-isolated DC/DC Switching RegulatorMornsun's K78 series is a high-efficiency switching regulator with the packages of SiP (system in package), SMD, or DFN, and the efficiency is up to 96%. They are designed as a pin-compatible replacement for LM78 linear regulators without any heatsink.

K78 series offers excellent performance and advantages - such as high efficiency, wide input voltage range, and highly accurate output voltage. An automated production factory can guarantee quality and reliability at a low cost. Such a perfect solution makes designing a switching regulator circuit redundant.

The regulated output K78-R4 series released has undergone a fundamental change in dimension and packaging which is manufactured via the chiplet SiP process, and the appearance of R4 has changed from simple and rough to refinement.
