Product data sheet
The TEA1532BT; TEA1532CT can operate in multi modes; see
In QR mode, the next converter stroke is started only after demagnetization of the
transformer current (zero current switching), while the drain voltage has reached the
lowest voltage to minimize switching losses (green function). The primary resonant circuit
of primary inductance and drain capacitor ensures this quasi-resonant operation. The
design can be optimized in such a way that zero voltage switching can extend over most of
the universal mains range.
