TMI3351 - Wide Input Range Buck Converter

General Description

The TMI3351 is an integrates 2-switchs synchronous buck converter mainly for widely varying input step-down regulator applications.

The control method is based upon current mode control that enables maximum performance under transient conditions.

The output voltage can be programmed by the FB pin.

Key Features

  • Wide Input Voltage Range from 4V to 32V.
  • Programmable VOUT Range from 0.8V to 30V.
  • Peak Current Mode Control.
  • Integrated Two low Rdson N-MOSFETs.
  • Adjustable Cycle-by-Cycle Current Limit by ILIM.
  • Adjustable Frequency: 100kHz~1MHz.
  • External Soft-Start Limits the Input Inrush Current.
  • Selectable FCCM or DCM with Pulse Skipping.
  • Cable Impedance Compensation.
  • Low Dropout Operation with Maximum Duty Cycle at 99.5%.
  • Input Under-Voltage Lockout.
