COMP (Pins A11, D11):
Current Control Threshold and fier. Internally, this pin is connected to VOUT with a 100k Error Amplifier Compensation Point. The current com- 0.5% precision resistor. Different output voltages can be parator threshold increases with this control voltage. The programmed with an additional resistor between the VFB voltage ranges from 0V to 2.4V with 0.7V corresponding and SGND pins. See the Applications Information section. to zero sense voltage (zero current).
MARG0 (Pin C12):
LSB Logic Input for the Margining
PGOOD (Pin G12):
Output Voltage Power Good Indicator. Function. Together with the MARG1 pin, the MARG0 pin Open-drain logic output that is pulled to ground when the will determine if a margin high, margin low, or no margin output voltage is not within ±10% of the regulation point, state is applied. The pin has an internal pull-down resistor after a 25µs power bad mask timer expires. of 50k. See the Applications Information section.
