SY8105 - Synchronous Step Down Regulator

Datasheet Summary

Description

The SY8105 is a high efficiency 500 kHz synchronous step-down DC-DC converter capable of delivering 5.0A current.

The SY8105 operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Features

  • low RDS(ON) for internal switches (top/bottom): 40mΩ/26mΩ.
  • 4.5-18V input voltage range.
  • 5.0A output current capability.
  • 500 kHz switching frequency.
  • Instant PWM architecture to achieve fast transient responses.
  • Internal softstart limits the inrush current.
  • Cycle-by-cycle peak current limitation.
  • 1.5% 0.6V reference.
  • TSOT23-6 package.
