Introduction
Following the success of the 1A N78xx non-isolated high-efficiency DC-DC switching regulator, MEAN WELL is proud to release the new N78xx-2 series—a 2A version offering increased power while maintaining compact size and high performance.
The N78xx-2 series is pin-to-pin compatible with traditional TO-220-packaged 78xx and 79xx linear regulators, making it an easy drop-in replacement. With efficiency reaching up to 96%, these modules eliminate the need for external heatsinks, significantly easing thermal management for engineers. This makes them an excellent choice for a wide range of applications including electronic instruments, embedded power systems, and distributed circuit architectures.
Additionally, the N78xx-2 series presents several advantages over the 78xx and 79xx series, as outlined in the table below:
Key Features
- Fully compatible pin layout with LM78xx/LM79xx linear regulators
- Compact, space-saving design
- Wide input voltage range up to 32V
- Operating temperature: -40℃ to +85℃ (natural convection)
- No heatsink required, even under full load
- Supports both positive and negative output voltage applications
- Meets BS EN/EN55032 Class B EMI standards without external component
