High-Performance Wide-VIN Synchronous Buck Regulators

Small, Flexible, Cost-Effective POL Power Solutions

TI provides the industry's most comprehensive portfolio of point-of-load regulators with a breadth of architectures to meet the demands of high-performance systems. Easy-to-use 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.

Featured Family of Wide Vin Buck Regulators

The established 100V family of synchronous wide VIN buck regulators, which include the LM5017/18/19 have now extended their family by introducing the new 48V buck regulators, including the LM25017/18/19. The 48V and 100V synchronous step-down regulators both include integrated high-side and low-side MOSFETs. The constant-on-time (COT) control scheme employed in all of these devices requires no loop compensation, provides excellent transient response, and enables very low step-down ratios.
