SY8009
Overview
The SY8009A and SY8009B are high-efficiency, high frequency synchronous step-down DC-DC regulator ICs capable of delivering up to 1.5A/2A output currents. The SY8009 family operate over a wide input voltage range from 3V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
- Low RDS(ON) for internal switches (top/bottom)
- SY8009A: 180mΩ/120mΩ, 1.5A, SOT23-5
- SY8009B:100mΩ/80mΩ,2.0A SOT23-6, SSOT23-6
- 3-5.5V input voltage range
- High switching frequency minimizes the external components
- SY8009A: 1.5MHz
- SY8009B: 1MHz
- Internal softstart limits the inrush current
- 100% dropout operation
- RoHS Compliant and Halogen Free
