P78W-500 DC-DC Converters

CUI Inc P78W-500 DC-DC Converters are compact and non-isolated DC-DC converters designed to offer a high-performance alternative to linear regulators. These converters feature a maximum output current of 0.5A and a wide input voltage range of 9VDC to 90VDC. The P78W-500 DC-DC converters are housed in a compact 3-pin SIP package and are pin compatible with LM78XX linear regulators. Additionally, the P78W-500 converters do not require a heat sink, making them ideal for applications where board space is limited and energy efficiency is a concern.
