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
