R-78E DC/DC Converter Switching Regulator Modules

RECOM Power R-78E DC/DC Converter Switching Regulator Modules are 0.5A or 1.0A, single-output DC/DC converters that provide a cost-effective option for high efficiency and accurate output voltage regulation. These modules feature an input voltage of 6V_DC to 28V_DC and up to 95% efficiency (no heat sink required) with an output voltage of 3.3V, 5V, 9V, 12V, or 15V. RECOM R-78E modules are housed in a compact 11.6mm x 8.5mm x 10.4mm, SIP3, TO-220 compatible package.
