Figure 20. Application Circuit Demonstrating Prebias Startup
Note
1. The prebias start-up feature is not compatible with Auto-Track. If the rise in the output is limited by the
voltage applied to the Track control pin, the output sinks current during the period that the Track control
voltage is below that of the back-feeding source. For this reason, it is recommended that Auto-Track be
disabled when not being used. This is accomplished by connecting the Track pin to the input voltage, VI. This
raises the Track pin voltage well above the set-point voltage prior to the module’s start up, thereby defeating
the Auto-Track feature.
