Two compact, isolated DC/DC converters from Dengrove Electronic Components deliver up to 10W from a 1.0 x 1.0 inch footprint, to save board space in equipment such as distributed power architectures, industrial controls and telecommunications equipment

With nominal input voltages of 12, 24 or 48V, the RP10-A and RP10-AW allow an input-voltage ratio of 2:1 and 4:1 respectively, giving a wide safety margin to handle large supply fluctuations. Single-output models have standard voltages from 3.3 to 24V, while complementary outputs range from ±5 to ±15V. The voltage can be trimmed over a range of ±10%, and low ripple and noise ensures the stability of powered equipment. The converters have typical efficiency of up to 91%, and no minimum load is required.

The converters have built-in class-B EMC filters, short-circuit, over-current and over-voltage protection, and under-voltage lockout. No additional external components are required, which not only minimises size but also simplifies design and enhances reliability, says the company. Six-sided continuous shielding maximises blocking of radiated noise, ensuring co-existence with external noise sources or sensitive equipment.

All units have 1.6kV isolation giving enhanced safety, are UL 60950-1 certified, and provide extra peace of mind through the manufacturer’s three-year warranty.
