SY8133 - Synchronous Step Down Regulator

Description

The SY8133 is a high efficiency 400 KHz synchronous step-down DC-DC converters capable of delivering 3A output current.

SY8133 operates over a wide input voltage range from 4V to 15V and integrate main switch and synchronous switch with very low Rds(on) to minimize the conduction loss.

Features

  • low Rds(on) for internal switches (top/bottom) 120/80 mΩ,.
  • 4-15V input voltage range.
  • 400KHz switching frequency.
  • Internal softstart limits the inrush current.
  • 2% 0.6V reference.
  • RoHS Compliant and Halogen Free.
  • Compact package: SO8 with exposed paddle Ordering Information SY8133.
  • (.
  • ).
  • Temperature Code C: -40°C~85°C Package Code: FC: SO8E Spec Code Typical.
