SY20306HDCC - High Efficiency 1.5MHz, Dual 1.5A Synchronous Step Down Regulator


·       Low RDS(ON) for internal switches (top/bottom):


·       2.5-5.5V input voltage range

·       1.5MHz switching frequency minimizes the external components

·       Internal softstart limits the inrush current

·       100% dropout operation

·       RoHS Compliant and Halogen Free

·       Compact and thermally enhanced package: DFN3x3-12

Typical Application


The SY20306H is a dual-output, high-efficiency 1.5MHz synchronous step-down DC-DC regulator capable of delivering up to 1.5A output current per output respectively.  The SY20306H operates 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.

Low output voltage ripple and small external inductor and capacitor sizes are achieved with 1.5MHz switching frequency.
