Introduction

AI Translation

The SY8089 and SY8089A are high-efficiency, high frequency synchronous step-down DC-DC regulator IC capable of delivering up to 2A output current. The SY8089 and SY8089A operate over a wide input voltage range from 2.7V 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. SY8089 integrates short circuit and over-voltage latch off protection.

Features

AI Translation
  • Low RDS(ON) for internal switches (top/bottom): 110mΩ/80mΩ
  • 2.7 - 5.5V input voltage range
  • 2A continuous, 3A peak load current capability
  • 1MHz switching frequency minimizes the external components
  • Internal softstart limits the inrush current
  • Reliable short circuit protection: SY8089: Latch off protection; SY8089A: Hic-cup mode protection
  • Reliable over-voltage protection: SY8089: Latch off protection; SY8089A: No latch off protection
  • 100% dropout operation
  • RoHS Compliant and Halogen Free
  • Compact package: SOT23-5
