SY98081全新原装SY98081QUC DFN 同步降压芯片 Silergy
税前: ¥3.00
General Description
SY98081/A/B/C/D/E/F are 3MHz, 0.6A synchronous step-down converters which integrates an inductor and a control IC in one tiny package (2.0mm×1.5mm, H=1.26mm). It can operate over a wide input voltage range from 2.5V to 5.5V and integrate main switch and synchronous switch with very low RDS (ON)to minimize the conduction loss.
Features
Low RDS(ON)for internal switches (top/bottom) 230mΩ/150mΩ
Integrate an inductor to minimizes the external components and PCB layout design
2.5~5.5V input voltage range
Output voltage:
﹣ SY98081: Output voltage adjustable
﹣ SY98081A: Fixed 1.2VOUT
﹣ SY98081B: Fixed 1.5VOUT
﹣ SY98081C: Fixed 1.8VOUT
﹣ SY98081D: Fixed 2.5VOUT
