MORNSUN adds a new switching regulator series K78xx-2000R3 rated at 2A to its non-isolated DC-DC converter family, which is designed to be a drop-in alternative to traditional 78xx series three-terminal linear regulators.

The series features an ultra-wide input voltage range of 6-36V, 0.1mA ultra-low no load input current, continuous short-circuit protection, low ripple noise (typ.: 30mV), etc.. The new 2A series can also accommodate operating temperature from -40°C to +85°C.

Besides, this series delivers efficiencies up to 95%, eliminates the need for a heat sink, cuts additional design space and installation cost, making it suitable for use in industrial control, medical, mining, railway and other related industries.
