SY8022中文资料High Efficiency 1 MHz, Dual 2.5A/2A Synchronous Step Down Regulator数据手册Silergy规格书

描述 Description

The SY8022 and SY8022L are high-efficiency 1MHz synchronous step-down DC-DC regulator ICs capableof delivering up to 2.5A output currents. The SY8022 operates 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 output voltage ripple and small external inductor and capacitor sizes are achieved with 1MHz switching frequency.

特性 Features

• low Rds(on) for internal switches (top/bottom):
\u0001·SY8022: 150/100mohm, 2.5A
\u0001·SY8022L: 180/120mohm, 2A
• 3-5.5V input voltage range
• 1MHz switching frequency minimizes the external components
• Internal softstart limits the inrush current
• 100% dropout operation
• Compact and thermally enhanced package: SO8E

应用 Application

• Access Point Router
• Net PC
• LCD TV
• Set Top Box
