LM5005MHX General Description

Offering a reliable solution for high voltage step-down regulation, Texas Instruments' LM5005MHX is capable of handling an input voltage range of 4.5V to 65V and delivering a continuous output current of 0.5A. With its fixed 75kHz switching frequency and internal 85mΩ N-channel MOSFET, this regulator ensures efficient power conversion, making it suitable for a wide range of applications with high input voltage requirements. The inclusion of protection features such as thermal shutdown, input undervoltage lockout, and cycle-by-cycle current limiting ensures safe operation under fault conditions, enhancing the device's robustness. Moreover, the LM5005MHX incorporates a precision internal reference with ±2% accuracy over the full operating temperature range, providing consistent performance. Its thermally enhanced 8-pin HTSSOP package further expands its versatility, making it suitable for space-constrained applications
