Summary and Features
 Dramatically simplifies off-line, power factor corrected, LED driver design
 Single-stage, power factor corrected, low component count, non-isolated LED driver
 Configurable for TRIAC dimming or non-dimming configurations
 PF >0.9 across line & load (non-dimming configuration)
 Eliminates all control loop compensation
 No output current sensing required
 High system efficiency both at 115 V and 230 V (>83% non-dimming configuration)
 Advanced performance features
 Compensates for inductance tolerance
 Compensates for input voltage variations
 Compensates for output voltage variations
 Frequency jittering greatly reduces EMI filter costs
 Advanced protection and safety features
 Auto-restart protection for short-circuit
 Hysteretic thermal shutdown
