The K78xx-2000R switching power module combines high efficiency and rugged reliability for demanding applications. Operating at up to 96% efficiency, it minimizes energy loss and eliminates the need for external heat sinks, ensuring cost-effective thermal management. Designed to withstand extreme environments, it functions seamlessly across a wide temperature range of -40℃ to +85℃, making it ideal for automotive, industrial, or outdoor systems. Its ultra-low no-load current of 0.2mA enhances energy savings in standby modes, while the wide input voltage range and robust 2000mA stabilized output support high-power requirements. The SIP3 packaging ensures a compact footprint, and LM78xx-series pin compatibility (with straight or curved pin options) allows effortless upgrades or replacements in existing designs. As a non-isolated, single-output solution, it delivers stable voltage regulation for telecom equipment, industrial automation, or high-density electronic systems, balancing power density, durability, and plug-and-play simplicity for engineers prioritizing performance and space optimization.
