Pin Function
Input supply voltage for the converter power stage.
Ground connection for the internal circuitry. AGND needs to be connected to PGND directly.
Power supply for the internal circuitry. Connect a 10 W resistor to PVIN and a 1 m F capacitor to AGND.
Control bit 0 - see Table 1 for decoding. This pin has a 1 MΩ internal pulldown resistor. This resistor is switched
in circuit whenever the EN pin is below the enable input high threshold, or when the part is in undervoltage
lockout.
Control bit 1 - see Table 1 for decoding. This pin has a 1 MΩ internal pulldown resistor. This resistor is switched
in circuit whenever the EN pin is below the enable input high threshold, or when the part is in undervoltage
lockout.
Control bit 2 - see Table 1 for decoding. This pin has a 1 MΩ internal pulldown resistor. This resistor is switched
in circuit whenever the EN pin is below the enable input high threshold, or when the part is in undervoltage
lockout.
Control bit 3 - see Table 1 for decoding. This pin has a 1 MΩ internal pulldown resistor. This resistor is switched
in circuit whenever the EN pin is below the enable input high threshold, or when the part is in undervoltage
lockout.
No connection.
Output voltage sense pin.
Ground connection for converter power stage.
Switching node - connect an inductor between this pin and the output capacitor.
