9 Application Information
Through setting the voltage on the V
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
0.484V. If the voltage on the control pin is higher than 1.312V, the output voltage is regulated at V
Before the control voltage is fed to the error amplifier inputs, the control voltage is clamped internal in the device.
