Stock Quantity: 0
The LC78_03-1.0 is a highly efficient, non-isolated Point-of-Load (PoL) DC-DC converter module designed for a wide input voltage range of 4.5V to 42V. It delivers a regulated 3.3V output at 1A, making it suitable for powering digital loads and embedded systems. The module boasts a peak efficiency of 93%, minimizing power dissipation and thermal stress. Its compact form factor and robust design allow for operation across a wide temperature range of -40°C to +85°C, ensuring reliable performance in harsh environments. The non-isolated topology provides a cost-effective solution for applications where isolation is not required. Integrated protection features include over-current protection (OCP) and short-circuit protection (SCP), enhancing system reliability. The module utilizes synchronous rectification for improved efficiency and features a low ripple output voltage.
