SY8009B中文资料High Efficiency 1.5MHz/1MHz, 1.5A/2ASynchronous Step Down Regulator 数据手册Silergy规格书

描述 Description

The SY8009A and SY8009B are high-efficiency, high frequency synchronous step-down DC-DC regulator ICs capable of delivering up to 1.5A/2A output currents. The SY8009 family operate 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 greater than 1MHz switching frequency

特性 Features

• Low RDS(ON) for internal switches (top/bottom)
• SY8009B:100mΩ/80mΩ,2.0A
• 3-5.5V input voltage range
• SY8009A: 1.5MHz
• Internal softstart limits the inrush current
• RoHS Compliant and Halogen Free
• Compact package: SOT23-5, SOT23-6 and Super
SOT23-6 are pin-compatible. Other packages are available upon requests

应用 Application

• LCD TV
• Net PC
• Access Point Router
