N78x 1A DC-DC Switching Regulators

MEAN WELL N78x 1A non-isolated DC-DC Switching Regulators offer a wide input range up to 36V, 3.3W to 15W options, and 500KHz switching frequency. The pin-out is fully compatible with traditional TO-220-packaged 78xx and 79xx linear voltage regulators, so it can be used as a drop-in replacement. These regulators feature high efficiency up to 96%, low ripple and noise, and a wide working temperature range of -40°C to +85°C. These models can be chosen positive or negative output voltage depending on the application. MEAN WELL N78x 1A DC-DC Switching Regulators are ideal for power supplies, industrial PCs, data communications, and microcontroller-related applications.
