Zero-voltage-switching resonant converter controller
Bridge frequency accuracy is optimum in the low frequency region. At higher frequencies
both the dead time and the oscillator frequency show a decay.
The frequency of the oscillator depends on the value of capacitor Cf, the peak-to-peak
voltage swing VCf and the charge and discharge currents. However, at higher frequencies
the accuracy decreases due to delays in the circuit.
8.6 Error amplier
The error amplier is a transconductance amplier. Thus the output current at pin VCO is
determined by the amplier transconductance and the differential voltage on input
pins I+ and I-. The output current IVCO is fed to the IRS input of the current-controlled
oscillator.
The source capability of the error amplier increases current in the IRS pin when the
differential input voltage is positive. Therefore the minimum current is determined by
resistor Rf(min) and the minimum frequency setting is independent of the characteristics of
the error amplier.
The error amplier has a maximum output current of 0.5 mA for an output voltage up to
2.5 V. If the source current decreases, the oscillator frequency also decreases resulting in
a higher regulated output voltage.
During start-up, the output voltage of the amplier is held at a constant value of 2.5 V. This
voltage level denes, together with resistor Rf, the initial switching frequency of the
TEA1610 after start-up.
8.7 Shut-down
The shut-down input (SD) has an accurate threshold level of 2.33 V. When the voltage on
input SD reaches 2.33 V, both power switches immediately switch off and the TEA1610
enters shut-down mode.
