9 Application Information

Through setting the voltage on the VCON pin (see Table 5) the output voltage of the AS1332 can be programmed from

1.3V (typ) to 3.16V (typ). This feature eliminates the need for external feedback resistors.

If the voltage on the control pin varies from 0.556V to 1.208V, the output voltage will change according to the equation

stated in Table 5. The output voltage is regulated at VFB,MIN as long as the voltage on the control pin is less than

0.484V. If the voltage on the control pin is higher than 1.312V, the output voltage is regulated at VFB,MAX.

Before the control voltage is fed to the error amplifier inputs, the control voltage is clamped internal in the device.
