TPS922052DRRR is a 12-pin WSON asynchronous buck LED driver for 4.5 V to 63 V inputs, with a 3 A typical switch limit and extensive PWM and analog dimming support.

Best for

  • Buck-driven LED strings
  • Common-anode LED connections
  • Fast PWM dimming
  • Constant-current or CC/CV designs

Avoid if

  • A guaranteed current capability above the device current-limit margin is required
  • Spread-spectrum switching is required for EMI reduction
  • The thermal pad cannot be properly soldered and cooled

Check before use

  • Input and LED output voltage range
  • Peak inductor current and saturation rating
  • RSENSE power dissipation
  • Thermal layout around the WSON exposed pad
