P78B-1000 Non-Isolated DC-DC Converters

CUI Inc P78B-1000 Non-Isolated DC-DC Converters provide a high-performance alternative to linear regulators and come housed in a compact 3-pin SIP package. The P78B-1000 series is pin-compatible with LM78xx model regulators and offers low ripple and noise. The P78 DC switching regulator does not require a heat sink, making it suitable for applications where board space is tight and energy efficiency is important. The commercial-grade DC-DC converters feature continuous short-circuit protection and are designed to meet EN/IEC 62368-1 safety standards. CUI Inc P78B-1000 Non-Isolated DC-DC Converters offer 1A current output, 36VDC maximum input voltage, and a -40°C to +90°C operating temperature range.
