R-78K DC/DC Converters

RECOM Power R-78K DC/DC Converters are available in 0.5A, 1A, and 2A versions with fixed outputs of 1.2V, 1.5V, 1.8V, 2.5V, and 6.5V, depending on the model, as well as traditional outputs of 3.3V, 5V, 9V, 12V, and 15V. The R-78K-0.5, R-78K-1.0, and R-78K-2.0 series all offer a wide input voltage range of 4.5V_DC to 36V_DC with efficiency of up to 95% or 96% and no need for heatsinks. The R-78K units have an ambient operating temperature range of -40°C to +90°C, including versions with no derating. Protections include undervoltage lockout and short circuits with automatic recovery. These SIP3 converters can meet EN 55032 class B EMC specifications with a simple input filter.
