产品概览
The TLV62084ADSGT from Texas Instruments is a 2A high-efficiency synchronous step-down converter with 2.7-6V input and 0.5-4V adjustable output in a 2x2mm WSON-8 package. Using DCS-Control architecture, it achieves up to 95% efficiency with 2MHz switching frequency and 100% duty cycle for lowest dropout.
