Storage Temperature Tstg
*1: The output current value may be limited depending on the duty ratio, ambient temperature, and heating condi-
tions. Do not exceed the junction temperature Tj under any circumstances.
• Power factor correction (PFC) application circuit
• Triac dimmer control application circuit
*2: The power dissipation PD depends on the pattern layout of the circuit board used.
■Applications
• LED light bulbs
• LED lighting equipment
