R-78CK-0.5 DC/DC Converters

RECOM Power R-78CK-0.5 DC/DC Converters provide a compact and efficient solution with a wide input range of 5V to 40V, up to 96% efficiency, and no need for heatsinks. These 0.5A switching regulators save space and energy while operating up to a +100°C ambient temperature. The pin-out is compatible with the LM78xx linear regulators for easy integration into existing designs. These non-isolated DC/DC converters offer short-circuit protection, thermal shutdown, and low ripple and noise for stable performance. The fixed output voltages of 3.3V, 5V, 12V, and 15V enable ease of use, and the series is certified by IEC/EN 62368-1. RECOM Power R-78CK-0.5 DC/DC Converters can also serve as positive-to-negative converters, making them ideal in circuits requiring a negative voltage source. Applications include industrial, automation, and test and measurement.
