FUNCTIONAL DESCRIPTION (continued)
Figure 1 shows a typical start up with the VIN5 and BP5 applied to the controller and then the EN/SYNC being
enabled. Shut down occurs when the VIN5 is removed
Figure 1. Startup and Shutdown Sequence
The unity gain differential amplifier with high bandwidth allows improved regulation at a user-defined point and
eases layout constraints. The output voltage is sensed between the VOUT and GSNS pins. The output voltage
programming divider is connected to the output of the amplifier (DIFFO).
If there is no need for a differential amplifer, the differential amplifier can be disabled by connecting the GSNS
pin to the BP5 pin and leaving VOUT and DIFFO open. The voltage programming divider in this case should be
connected directly to the output of the converter.
Figure 2. Differential Amplifier Configuration
Because of the resistor configuration of the differential amplifier, the input impedance must be kept very low or
there will be error in setting the output voltage.
