TMI3255S - 5A Synchronous COT Step-Down Converter

General Description

The TMI3255S is a high efficiency, Constant onTime (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 5A current.

TMI3255S integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Key Features

  • 39mΩ/20mΩ Low RDS(ON) internal FETs.
  • High Efficiency Synchronous-Mode Operation.
  • Wide Input Range: 4.5V to 18V.
  • Feedback Voltage Accuracy 0.6V±1.5%.
  • 600kHz Switch Frequency Typical.
  • Up to 5A Output Current.
  • COT control to achieve fast transient responses.
  • Power Save Mode at Light Load.
  • Integrated internal compensation.
  • Stable with Low ESR Ceramic Output Capacitors.
  • Over Current Protection with Hiccup Mode.
  • Thermal Shutdown.
  • Inrush.
