LED Drivers

automotiveLED driverboost converterSEPICfour channelPWM dimmingHTSSOP-20

TPS61194PWPRQ1 is a four-channel automotive LED driver with integrated boost/SEPIC power conversion for LED strings up to 100 mA per channel.

Best for

  • Four-string automotive LED backlights
  • Automotive displays requiring PWM dimming
  • Boost or SEPIC LED-string supplies

Avoid if

  • More than 100 mA is required from an individual uncombined channel
  • The application cannot provide suitable automotive input transient protection
  • A non-switching LED driver is required

Check before use

  • Confirm maximum LED-string voltage remains within the 45 V converter output limit.
  • Confirm the application VIN range remains within recommended operating conditions.
  • Connect unused current-sink outputs to ground.
  • Use the required LDO bypass capacitor close to the LDO pin.
