Texas Instruments (TI) today 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.
Pricing and availability
Available through the TI store and authorized distributors, the 100-V LM5164 and LM5164-Q1 are priced in small reels at US$1.53 and US$2.04, respectively, for 1,000-unit quantities. The LM5164-Q1EVM-041 evaluation module is available for US$75.
