LED driverboostbuck-boost65 VPWM dimmingspread spectrumWSON-12

TPS923653DRRR is a 65 V-class asynchronous boost or buck-boost LED driver with a 3 A typical switch-current limit and spread-spectrum switching.

Best for

  • Wide-input LED lighting systems
  • Boost LED strings
  • Buck-boost LED drivers
  • Applications needing rapid PWM dimming

Avoid if

  • A synchronous power stage is required
  • The required switch current exceeds the device current-limit margin
  • A validated DigiKey category mapping is required before publication

Check before use

  • Confirm the 4.5 V to 63 V input operating range covers all transients.
  • Set LED current using the 200 mV current-sense reference.
  • Choose RFSET for the required 100 kHz to 2.2 MHz switching frequency.
  • Provide thermal copper and solder the exposed pad.
