R-78T 1.0A Switching Regulator DC-DC Converters

RECOM Power R-78T 1.0A Switching Regulator DC-DC Converters offer a wide input voltage range, efficiency up to 95%, and a low profile SMD package. Three output voltages are available as standard: 3.3V, 5V, and 12V. Due to a 1.5A start-up overload capability, the R-78T converters can be used to replace 1A or 1.5A regulators in many applications. These modules come with three different styles to be pin-compatible with existing solutions, but at a lower cost.
