SY20111B
Description
SY20111A/B/C/D/E/F are high efficiency 3MHz synchronous step down DC/DC regulator ICs capable of delivering up to 1A output current. 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.
Key Features
- Low RDS(ON) for internal switches (top/bottom) 230mΩ/150mΩ
- 2.5~5.5V input voltage range
- Fixed output voltage: ﹣ SY20111A: Fixed 1.2VOUT ﹣ SY20111B: Fixed 1.5VOUT ﹣ SY20111C: Fixed 1.8VOUT ﹣ SY20111D: Fixed 2.5VOUT ﹣ SY20111E: Fixed 3.3VOUT ﹣ SY20111F: Fixed 1.0VOUT
- High switching frequency 3MHz minimizes the external components
- Internal soft-start limits the inrush current
