Typical Application


The SY20616B2 is a high efficiency 1.5MHz 6A synchronous step down DC/DC regulator which integrates an inductor and a control IC in one tiny package (4.0mm×3.0mm, H=2.0mm). It can operate over a wide input voltage range from 2.7V to 5.5V and integrate main switch and synchronous switch with very low RDS (ON) to minimize the conduction loss. The output voltage can be programmed from 0.6V to 1.5V through I2C interface.
