MORNSUN Non-isolated DC-DC converter-0.5-3A Switching Regulator DFN Package
MORNSUN's switching regulator K78 series represents a family of high-efficiency, non-isolated DC-DC converters available in a variety of packages including SIP, SMD, chassis mounting, and open frame, with efficiency up to 95%. The series is known for features such as ultra-low no-load input current, low radiation, and no requirement for external heat sinks, making it ideal for industrial control, instrumentation, and power electronics applications.
The newest R4 series features an ultra-small, ultra-thin DFN package (9.00 x 7.00 x 3.10mm) specifically designed for SMD manufacturing processes. This series combines high efficiency (up to 92%), extremely low no-load input current (as low as 0.1mA), and short-circuit protection, all while requiring no external heat sink. These compact converters are widely used in industries such as industrial control, electric power, and instrumentation.
Product Features:
- Ultra-small, ultra-thin DFN package (9.00 x 7.00 x 3.10mm) available for SMD processes
- Operating temperature range: -40℃ to +105℃
- Efficiency up to 92%
- No-load input current as low as 0.1mA
- Short-circuit protection, no external heat sink required
- Compliant with AEC-Q100 automotive standard (under testing)
- Wide range of package options including DFN, SIP, SMD, chassis mounting, and open frame
