TMI3252SH - 1MHz 18V 2A Synchronous COT Step-Down Converter

General Description

The TMI3252SH is a high efficiency 1MHz, Constant-on-Time (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 2A current.

TMI3252SH integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Key Features

  • 140mΩ/70mΩ Low RDS(ON) internal FETs.
  • High Efficiency Synchronous-Mode Operation.
  • Wide Input Range: 4.5V to 18V.
  • Output Voltage from 0.6V.
  • 1MHz Switch Frequency.
  • Up to 2A 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 Current Limit and S.
