TRIAC Dimmable LED Lighting Driver IC

The TS19320CS – a phase-cut (TRIAC) dimmable constant current control IC with active power factor correction (PFC) for isolated or non-isolated AC-DC LED lighting control.

- Configurable as an isolated, primary-side-regulated flyback controller or non-isolated buck-boost converter.
 – Compatible with many types of TRIAC leading-edge and trailing-edge dimmers.
 – High power factor and low total harmonic distortion (THD)

Features:

  • Constant current accuracy <±5%
  • Flyback or Buck-Boost w/o photocoupler
  • Good dimmer compatibility for 120/230VAC Lamps
  • Boundary-mode PFC operation
  • Built-in active power factor correction
  • High voltage (500V) startup circuit
  • Open-LED demagnetization (DMG) protection, VCC over-voltage protection (OVP), over-temperature protection (OTP), shorted-LED Protection
  • Cycle-by-cycle current limit
  • Gate drive voltage clamping

Applications:

  • LED lighting
  • Down lights, Tube lamps, PAR Lamps, Bulbs
