Application Notes
The FG pin is an open-drain output. A resistor can be used to pull up the FG voltage to the
appropriate level, which depends on the voltage level of the monitoring/control system.
Without the additional pull-up resistor, the FG voltage will be V
The power dissipated by the IC varies widely with the supply voltage, the output current, and
loading.
