APPLICATION INFORMATION

error amplifier output stage

The UCC3810 error amplifiers are operational amplifiers with low-output resistance and high-input resistance.

The output stage of one error amplifier is shown in Figure 3. This output stage allows the error amplifier output

to swing close to GND and as high as one diode drop below 5 V with little loss in amplifier performance.
