High-Voltage Point-of-Load Power Solutions

High-Performance and Ease-of-Use Above 65V

TI provides the industry's most comprehensive portfolio of high-voltage point-of-load regulators with a breadth of architectures to meet the demands of high-performance systems. Easy-to-use, high-voltage converters and controllers simplify DC-DC conversion and reduce solution size while delivering increased system reliability and efficiency. Constant on-time and emulated current mode control architectures offer stability for very high step-down ratios with minimal external components required to complete the design. With maximum operating input voltages of up to 100V, your system is protected against even the harshest transient conditions present in rugged Telecom, Industrial, Solar, and Automotive environments. TI's LM500x and LM501x converters and LM511x controllers are the premier high-voltage point-of-load regulators on the market today.
