The K78xx-500R3 switching power module delivers high-performance power conversion with exceptional versatility. Operating across a wide temperature range of -40℃ to +85℃, it ensures reliable performance in harsh environments without requiring external heat sinks, simplifying installation and reducing costs. With up to 96% efficiency, it minimizes energy loss and heat generation, making it ideal for energy-sensitive applications. Its ultra-low no-load current of 0.2mA further enhances energy savings in standby modes. Designed for flexibility, the module supports a broad input voltage range and provides a stable single output of 500mA, catering to diverse industrial and embedded systems. The SIP3 packaging ensures a compact footprint, while its non-isolated, stabilized output guarantees consistent voltage regulation. Pins are fully compatible with the K78xx series, offering seamless integration into existing designs with options for straight or curved pin configurations. Whether deployed in automotive electronics, IoT devices, or industrial automation, the K78xx-500R3 combines ruggedness, efficiency, and plug-and-play compatibility, streamlining upgrades and reducing time-to-market for power-critical solutions.
