Typical DVD switching power supply circuit
Shown is the standby power supply circuit in digital products, which adopts the structure of a switching power supply. The switching oscillation integrated circuit
TEA1623 provides oscillation pulses for the switching transformer . The secondary output of the switching transformer is rectified and filtered to form a +5 V voltage, which
supplies power to the microprocessor control circuit.
