Fig 12. Lamp current control
The output of the OTA is connected to pin CIFB. The external capacitor C ext(CIFB) is
charged and discharged according to the voltage on the OTA inputs and the
transconductance of the OTA, g m(IFB) according to the formula:
I CIFB = g m(IFB) ? (V IFB ? V reg(IFB ).
More components can be connected to pin CIFB to improve the response time and
stability of the lamp current control loop.
Pin CIFB is connected to the input of the VCO (Voltage Controlled Oscillator) that
determines the frequency of the IC. Pin CIFB voltage is inversely proportional to the
switching frequency. When the load is inductive, an increase in frequency decreases the
lamp current, and a decrease in frequency increases the lamp current. With the closed
loop for the lamp current in place, the IC will regulate to the required frequency for the
desired lamp current. So when the IC enters Burn state it will go to either point D or H
shown in Figure 10 (UBA2015A) or Figure 11 (UBA2016A) depending on the DIM input
voltage.
