SY20334 Overview
Description
The SY20334 is a dual-output, high-efficiency 1.5MHz synchronous step-down DC-DC IC capable of delivering up to 3A output current per output respectively. The SY20334 operates over a wide input voltage range from 2.7V to 5.5V and integrates 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): 105/85mΩ
- 2.7-5.5V input voltage range
- 1.5MHz switching frequency minimizes the external components
- Internal soft-start limits the inrush current
- 100% dropout operation
