The TLD5191ES is a synchronous MOSFET H-Bridge DC-DC controller for high power LED driving. It offers analog/digital dimming, adjustable switching frequency (200 kHz to 700 kHz), and spread spectrum modulation for improved EMC behavior. The current mode regulation ensures stability with small external components. The controller has built-in protection features, adjustable soft start, and is suitable for automotive and industrial applications.

Features

  • MOSFET H-Bridge with single inductor
  • Constant current & constant V regulation
  • Wide VIN range (Device 4.5V to 40V)
  • Wide LED forward V R (2V up to 55V)
  • LED current accuracy+/-3% at Tj=25°
  • Frequency range from 200kHz to 700kHz
  • Spread spectrum always active
  • Overvoltage, shorted LED fault
  • Adjustable soft start
  • Dimming features: analog & PWM dimming
  • Small thermally enhanced TSDSO-24package

Benefits

  • Compact Design Enable by High Efficiency
  • Reliable load diagnosis; easy to use.
