PSB2120 General Description

The reference provides a 4.0 V voltage for the regulation loop. A high gain error amplifier compares the reference voltage with the switch mode supply output voltage. The output of the error amplifier is compared with a periodic linear ramp, which is generated by the sawtooth-oscillator circuit. The.
