Texas Instruments TPS40040DRBTG4 is a high-performance, non-synchronous buck controller designed for efficient step-down DC-DC conversion. This versatile device operates from a 2.25V to 5.5V supply voltage and features a 300kHz switching frequency, enabling the use of smaller passive components. The TPS40040DRBTG4 supports a maximum duty cycle of 95%, ideal for applications requiring deep voltage reduction. Its output configuration is positive, and it functions as a transistor driver with a single output phase. The controller incorporates an Enable pin for flexible power sequencing. The 8-SON (3x3) package with an exposed pad ensures effective thermal management. This component is commonly employed in power supply designs for consumer electronics, industrial automation, and automotive systems. The TPS40040DRBTG4 is supplied in tape and reel packaging.
