Robust 100-V, 1-A synchronous buck converter enables designers to shrink board space

22.03. 2019 | News

Texas Instruments introduced a wide-input-voltage (VIN) synchronous DC/DC buck converter with the industry’s best combination of light load efficiency, ease of design and overall power solution cost. The 100-V, 1-A LM5164 step-down voltage converter shrinks board space in rugged battery-powered industrial and automotive power supplies. Used in conjunction with TI’s WEBENCH® Power Designer, this new DC/DC converter can enable simpler, faster power conversion design.

The LM5164 is an easy-to-use, ultra-low quiescent current (IQ) synchronous step-down buck regulator that features a constant on-time (COT) control architecture and integrates high- and low-side power MOSFETs. The highly efficient buck converter operates from a wide input voltage of 6 V to 100 V and delivers up to a 1-A DC load current. The COT architecture requires no external compensation, while an internal VCC bias supply and bootstrap diode eliminates an additional capacitor (more info).
