概述
Description
Key features include a high switching frequency of up to 2.1MHz, which reduces the size of the external components and allows for a compact design. It also incorporates built-in protection features like cycle-by-cycle current limiting, thermal shutdown, and output overvoltage protection, enhancing reliability and safety. The LMR16030PDDA is available in a thermally enhanced 8-pin PowerPAD™ package, which aids in efficient heat dissipation. This converter is ideal for designers seeking a compact, efficient solution for high-voltage, low-current power supply requirements.
