Phase Control Voltage Inverter Control IC

LA5663V

(3) RECT_C pin

COMP1 rectifies the CCFL current waveform, plus bias VBE, from the IFB pin. ANDing this waveform voltage with

that from point A (this latter has the same phase as NGATE2) averages the two, producing phase difference voltage

output from the RECT_C pin.

(4) V_PHASE and FLOOP_C pins

COMP2 controls the VCO frequency so that the RECT_C and V_PHASE pins have the same voltage. The RECT_C

pin voltage represents a phase difference voltage, so changing the V_PHASE pin voltage adjusts the phase difference.

* The above graph is based on measurements for the IC in isolation. Actual phase difference adjustment requires

connection to the piezoelectric transformer.
