Product Summary

The L6563 is a current-mode PFC controller operating in Transition Mode (TM). Based on the core of a standard TM PFC controller, the L6563 offers improved performance and additional functions.The output voltage is controlled by means of a voltage-mode error amplifier and a precise (1.5% @TJ = 25℃) internal voltage reference. The stability of the loop and the transient response to sudden mains voltage changes are improved by the voltage feedforward function (1/V2 correction). Additionally, the L6563 provides the option for tracking boost operation (where the output voltage is changed tracking the mains voltage). The L6563 features extremely low consumption (≤ 90 μA before start-up and ≤ 5 mA running).

Parametrics

L6563 absolute maximum ratings: (1)VCC, pin 14 IC supply voltage (Icc = 20mA): self-limited V; (2)pin 2, 4 to 6, 8 to 10 Analog inputs & outputs: -0.3 to 8 V; (3)pin 1, 3, 7 Max. pin voltage (Ipin = 1 mA): Self-limited V; (4)IPWM_STOP, pin 10 Max. sink current: 3 mA; (5)IZCD, pin 9 Zero current detector max. current: -10 (source), 10 (sink)mA; (6)PTOT, Power dissipation @TA = 50℃: 0.75 W; (7)TJ, Junction temperature operating range: -25 to 150℃; (8)TSTG, Storage temperature: -55 to 150℃.
