主要应用
概述
The SY8031 is a high-efficiency 2.25MHz synchronous step-down DC-DC converters capable of delivering 0.6A/1.2A output current. SY8031 operates over a wide input voltage range from 2.5V to 5.5V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
Applications
• WiFi Card
• Set Top Box
• GPS
• Toy
