Regulated Output (0.5-10A)

MORNSUN switching regulator K78 series is the high efficiency non-isolated dcdc converter with the package of SIP, SMD, chassing mounting or open frame, and the efficiency can up to 95%. The K78 series includes other features, such as 0.2mA no-load input current, low radiation and no heat sink requirement, which is ideal for industrial control, instrumentation and power electronics application and so on. The newest R4 series features ultra-small, ultra-thin DFN package which is available for SMD manufacturing processes.
