Silergy SY20611
The SY20611 is a 3MHz, 1.2A synchronous step-down converter which integrates an inductor and a control IC in one tiny package (2.5mm×2.0mm, H=1.15mm). It can operate over a wide input voltage range from 2.5V to 5.5V and integrates main switch and a synchronous switch with very low RDSON to minimize the conduction loss.| Part No. | SY20611 |
