SOP-8

Pin Definition:

1. HV	8. GND
2. RT	7. OUT
3. CS	6. VCC
4. COM	5. DMG

The TS19320CS is a phase-cut (TRIAC) dimmable constant current control IC with active power factor correction for isolated or non-isolated AC-DC LED lighting. It supports Flyback or Buck-Boost configurations and is compatible with leading-edge and trailing-edge TRIAC dimmers. It guarantees constant current accuracy to < ± 5% using Boundary Conduction Mode (BCM) operation.

Features:

· Constant current accuracy < ± 5%
· Flyback or Buck-Boost w/o photocoupler
· Good dimmer compatibility for 120/230V AC 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
