TH1200F - 350mA High Efficiency Step Down LED Driver

General Description

The TH1200F is a high efficiency step-down converter optimized to drive high current LEDs.

A patented switching control algorithm allows highly efficient and accurate LED current regulation.

A single RSET resistor sets the full scale LED string current up to 350mA from supplies as high as 36V.

Key Features

  • LED drive current up to 350mA.
  • Compatible with 12V and 24V standard systems.
  • Handles transients up to 40V.
  • Single Pin Control and Dimming function.
  • Power Efficiency up to 94%.
  • Drives LED strings of up to 32V.
  • Open and short LED protection.
  • Parallel configuration for higher output current.
  • RoHS-compliant TSOT-23 5-lead package.
