RECOM launches the REC8E range of low-cost, high-efficiency, 8W DC/DC converters specially designed for battery-powered applications. Three input voltage ranges are available: 9-18V (12V systems), 18-36V (24V systems) and 20-60V (48V systems), the latter matching the LV 148 requirements for 48V Li-ion voltages in vehicles. To avoid a damaging deep discharge, under-voltage lockout is included to automatically switch off the converter if the battery voltage falls below safe levels. Fully protected output voltages are available: 5V, 9V, 12V, 15V, 24V, +/-12V and +/-15V. All outputs are tightly regulated and can drive high capacitive loads over a wide temperature range of -40°C to +75°C without derating. An on/off control pin is fitted as standard to reduce the supply current to less than 0.7mA in shutdown mode.
EMI from the REC8E is very low, with only simple, low-cost external components required for compliance with EN 55032 class A or B emission limits. Isolation rating is 1.6kV/1 minute, and the devices are certified to UL/IEC/EN 62368-1.
The REC8E is available in an industry-standard 1”x1” low profile, non-metallic package, suitable for use in high density PCBs.
“This latest addition to our Econoline series is a great combination of performance and value” commented Steve Roberts, Innovation Manager of RECOM, “It suits 48V Li-ion inputs in e-mobility as well as in general industry and test and measurement applications”.
