主要应用
概述
The SY8012A is a high-efficiency 1MHz synchronous step-down DC-DC regulator IC capable of delivering up to 2A output current respectively. The SY8012A operates over a wide input voltage range from 3V to 5.5V and integrates 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 MHz switching frequency.
Applications
- Set Top Box
- LCD TV
- Access Point Router
- Mini-notebook PC
- Net PC
