Figure 11. Open Loop Test Circuit
Note: The CS3524A should be able to be tested in any
3524 test circuit with two possible exceptions:
1. The higher gain−bandwidth of the current limit
amplifier in the CS3524A may cause oscillations in
an uncompensated 3524 test circuit.
2. The effect of the shutdown cannot be seen at the
compensation terminal, but must be observed at the
outputs.
