产品概览
The TPS62802YKAR from Texas Instruments is an ultra-low quiescent current step-down converter operating from 1.75V to 5.5V input, delivering up to 1A output. With only 2.3μA operating quiescent current and 4MHz switching frequency, it achieves extremely small solution size in a 0.7×1.05mm DSBGA-6 package. The innovative R2D converter allows flexible output voltage selection via a single external resistor.
