After the launch of the 1A non-isolated miniaturized high efficiency DC-DC switching regulator N78xx series, MEAN WELL has introduced a new 2A model, the N78xx-2 series. This new series is designed to be fully pin-compatible with the traditional TO-220 packaged 78xx and 79xx linear voltage regulators, facilitating direct replacement. The key benefits of the N78xx-2 series include an efficiency of up to 96% and eliminating the need for additional heatsinking, which simplifies heat management for system designers. It is particularly well-suited for integration into various electronic instruments, power supplies, and distributed circuit systems.
Additionally, the N78xx-2 series presents several advantages over the 78xx and 79xx series, as outlined in the table below:
