This is the common ground connection for the VI and VO power connections. It is also the 0 Vdc GND 1,7 reference for the control inputs. VI 2 The positive input voltage power node to the module, which is referenced to common GND. The Inhibit pin is an open-collector/drain negative logic input that is referenced to GND. Applying a low-level ground signal to this input disables the module’s output and turns off the output voltage. Inhibit(20) 3 When the Inhibit control is active, the input current drawn by the regulator is significantly reduced. If the inhibit feature is not used, the control pin should be left open-circuit. The module then produces an output whenever a valid input source is applied. A 1% resistor must be directly connected between this pin and GND (pin 1) to set the output voltage of the module higher than its lowest value. The temperature stability of the resistor should be 100 ppm/°C (or better). The set-point range is 1.2 V to 5.5 V for W-suffix devices, and 0.8 V to 1.8 V for L-suffix VO Adjust 4 devices. The resistor value required for a given output voltage may be calculated using a formula. If left open circuit, the output voltage defaults to its lowest value. For further information on output voltage adjustment, see the related application section. The specification table gives the preferred resistor values for a number of standard output voltages. The sense input allows the regulation circuit to compensate for voltage drop between the module and VO Sense 5 the load. For optimal voltage accuracy, VO Sense should be connected to VO. It can also be left disconnected. VO 6 The regulated positive power output with respect to the GND node. This is an analog control input that enables the output voltage to follow an external voltage. This pin becomes active typically 20 ms after the input voltage has been applied, and allows direct control of the output voltage from 0 V up to the nominal set-point voltage. Within this range the output will follow the voltage at the Track pin on a volt-for-volt basis. When the control voltage is raised above this Track 8 range, the module regulates at its set-point voltage. The feature allows the output voltage to rise simultaneously with other modules powered from the same input bus. If unused, this input should be connected to Vi. Note: Due to the undervoltage lockout feature, the output of the module cannot follow its own input voltage during power up. When this input is asserted to GND, the output voltage is decreased by 5% from the nominal. The input requires an open-collector (open-drain) interface. It is not TTL compatible. A lower percent Margin Down(1) 9 change can be accomodated with a series resistor. For further information, see the related application section. When this input is asserted to GND, the output voltage is increased by 5%. The input requires an Margin Up(1) 10 open-collector (open-drain) interface. It is not TTL compatible. The percent change can be reduced with a series resistor. For further information, see the related application section.
