TPS61194 - High-Performance Four-Channel LED Driver

Description

The TPS61194 is a high-efficiency, low-EMI, easy-touse LED driver with flexibility to support a wide range of applications.

It has four high-precision current sinks that can be combined for higher current capability.

Features

  • Input voltage operating range 4.5 V to 40 V.
  • Four high-precision current sinks.
  • Current matching 1% (typical).
  • LED string current up to 100 ma per channel.
  • Outputs can be combined externally for higher current per string.
  • High dimming ratio of 10 000:1 at 100 Hz.
  • Integrated boost/SEPIC converter for led string power.
  • Output voltage up to 45 V.
  • Switching frequency 300 kHz to 2.2 MHz.
  • Switching synchronizati.
