Stock Quantity: 0
The LC78_03-3.0 is a highly efficient, non-isolated Point-of-Load (PoL) DC-DC converter module designed for demanding embedded applications. It delivers a regulated 3.3V output at 3A from a wide input voltage range of 4.5V to 28V. This module utilizes synchronous rectification topology to achieve a peak efficiency of 95%, minimizing power dissipation and enabling high power density. Robust thermal performance is guaranteed across an operating temperature range of -40°C to +85°C, making it suitable for harsh environments. The compact form factor facilitates easy integration into existing systems. Key features include over-current protection (OCP), short-circuit protection (SCP), and over-temperature protection (OTP), ensuring reliable operation and system safety. The module is designed for high reliability and long operational life, utilizing high-quality components and rigorous testing procedures. The non-isolated design allows for flexibility in grounding configurations.
