Switching power supply circuit using TEA2260-61 and TEA5170 combination
Shown is a switching power supply circuit using a combination of TEA2260/61 and TEA5170 . 'rEA2260/61 is a switching and oscillation voltage stabilizing
control integrated circuit pin output pulse excitation signal , which is added to the base of the switching transistor to cause the switching tube to output switching pulses. The secondary TEA5170
outputs horizontal pulses from the @ pin under the stimulation of the horizontal synchronization pulse, and provides synchronization pulses to the TE A2260/61@ pin through the pulse transformer, so that the oscillation
of the switching power supply is the same as the horizontal frequency.
