Step-down converter ML-1280

printed circuitembeddedvehicle

Overview
Winmate ML-1280 is a DC/DC power converter module engineered for military and defense power systems, compliant with MIL-STD-1275E. It integrates a surge-stopper circuit, a 6600W transient voltage suppressor and eFuse protection to mitigate voltage spikes, reverse polarity and thermal/overload events. The unit accepts 9–36V DC input and supports typical outputs such as 12V @ 6.67A (80W).

Key features

• MIL-STD-1275E compliant
• High-efficiency DC-DC power conversion (up to 90% at full load)
• Wide input range: 9–36V DC
• Low inrush current design
• Output over-current protection (OCP) and output regulation
• Input reverse polarity protection
• Surge-stopper circuit and 6600W transient voltage suppressor (TVS)
• Comprehensive eFuse protection (under-voltage, over-voltage, overload, over-temperature)

Certifications

• MIL-STD-1275E
• FCC
• CE
