LED Drivers

automotiveLED driversynchronous buck3 AHTSSOP-16

TPS92643QPWPRQ1 is a 3 A automotive synchronous buck LED driver with wide input range, adaptive switching control, analog/PWM dimming, and fault indication.

Best for

  • Automotive headlamp LED modules
  • Automotive fog-lamp LED modules
  • Wide-input constant-current LED drive

Avoid if

  • The design requires a package other than 16-pin HTSSOP
  • The required LED current exceeds 3 A continuous

Check before use

  • AEC-Q100 and operating-temperature requirements
  • LED stack voltage versus VIN
  • Inductor peak current and current-sense dissipation
  • PWM dimming frequency and bootstrap capacitor
