The H100EI series of high isolation 1W DC/DC converters from MicroPower Direct is specifically designed for space critical applications and offers a combination of miniature size, input and output isolation and model selection. There are 15 models that operate from 3.3, 5, 12 and 24V DC inputs and provide single outputs of 3.3, 5, 9, 12, or 15V DC. Standard features include an input and output isolation of 3 000V DC and have a MTBF of over 3.5Mhours. The converters are packaged in a 0.50x0.394x0.303inch encapsulated case. Each model operates from -40 to +85°C with no derating or heat sinking required. The converters are suitable for applications requiring 1W of output power such as test instrumentation, data acquisition subsystems, and battery-backed equipment.
