TEA1610P; TEA1610T
Zero-voltage-switching resonant converter controller
12. Application information
An application example of a zero-voltage switching resonant converter application using
TEA1610 is shown in Figure 10. In the off-mode the VDD voltage is pulled below the stop
level of 9.4 V by the 7.5 V Zener diode and the half-bridge is not driven. In the on-mode
the TEA1610 starts-up with a high-ohmic bleeder resistor. After passing the level for start
of oscillation, the TEA1610 is in normal operating mode and consumes the normal supply
current delivered by the 12 V supply. The dead time is set by Rdt and Cf. The minimum
frequency is adjusted by Rf(min) and the frequency range is set by Rf. The output voltage
is adjusted with a potentiometer connected to the inverting input of the error amplier and
is regulated via a feedback circuit. The shut-down input is used for overvoltage protection.
To prevent interference, lter capacitors can be added on pins IFS, IRS and VREF. The
maximum value of each lter capacitor is 100 pF.
Practical values of the application example are given in Figure 9, in which the measured
oscillator frequency with capacitor Cf = 220 pF is shown as a function of the charge
current IIRS. Note that the slope of the measured frequency differs from the theoretical
frequency (frequency set) calculated as described in Section 8.5 “Maximum frequency
The measured dead time is directly related to the charge current (total current owing into
pin IRS) and therefore to the oscillator frequency.
The measured frequency graph can be used to determine the required Rf resistor for a
certain maximum frequency in an application with the same value of capacitor Cf.
More application information can be found in application note
AN99011.
