供应 SY8009BABC 同步整流降压稳压器

SY8009B General 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 R DS(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.

SY8009B Features

• Low R DS(ON) for internal switches (top/bottom)

•  SY8009A: 180mΩ/120mΩ, 1.5A, SOT23-5

•  SY8009B:100mΩ/80mΩ,2.0A SOT23-6, SSOT23-6

• 3-5.5V input voltage range

• High switching frequency minimizes the external components

•  SY8009A: 1.5MHz

•  SY8009B: 1MHz

• Internal softstart limits the inrush current

• 100% dropout operation

• RoHS Compliant and Halogen Free

• Compact package: SOT23-5, SOT23-6 and Super SOT23-6 are pin-compatible. Other packages are

available upon requests
