High-efficiency non-isolated step-down DC-DC converters with 250W output, wide input range, and multiple package options.
The i6A4W Series is a family of non-isolated step-down DC-DC converters designed for high-current output voltages from single 12V, 24V, or 48V AC-DC supplies. It offers high efficiency (up to 97%) and a wide input voltage range (9–53V). The series supports multiple output voltage ranges and package options including 1/16th brick and SIP. Minimal external components are required, and the design supports easy thermal management and reduced board area. Applications include industrial and commercial power systems requiring compact, high-density power conversion.
Key features include high power density, low airflow requirements, and one part for multiple applications. The series is available in DIP and SIP packages with options for remote on/off, sense, and power good. Safety certifications include IEC/UL/CSA/EN 60950-1 and CE Mark (LVD and RoHS).
