4863G

The 4863G is short for TDA4863G. It is a kind of power factor controller IC for high power factor and low THD. The device controls a boost converter in a way that sinusoidal current is taken from the single phase line supply and stabilized DC voltage is available at the output. Furthermore, 4863G is available in P-DSO-8-3 package.

There are some features of 4863G as follows: (1)IC for sinusoidal line-current consumption; (2)power factor achieves nearly 1; (3)controls boost converter as active harmonic filter for low THD; (4)start up with low current consumption; (5)zero current detector for discontinuous operation mode; (6)output overvoltage protection; (7)output undervoltage lockout; (8)Internal start up timer; (9)totem pole output with active shut down; (10)internal leading edge blanking LEB.

What comes next is about the maximum ratings of 4863G: (1)supply+zener current, ICCH+IZ: 20 mA max; (2)supply voltage, VCC: -0.3 to VZ V when VZ=Zener Voltage, ICC+IZ=20 mA; (3)voltage at pin 1,3,4: -0.3 to 6.5 V; (4)current into pin 2, IVAOUT: 40 mA max at VVAOUT=4 V, VVSENSE=2.8 V and -10 mA min at VVAOUT=0 V, VVSENSE=2.3 V, t<1 ms; (5)current into pin 7, IGTDRV: -500 to 500 mA at t<1 ms; (6)current into pin 5, IDETIN: 10 mA max at DETIN>6 V and -10 mA at DETIN<0.4 V, t<1 m; (7)storage temperature,Tstg: -50 to 150; (8)operating junction temperature, TJ: -40 to 150; (9)thermal resistance junction-ambient, RthJA: 100 K/W.
