Pin Function
Channel A. Input supply voltage for the converter power stage and internal circuitry.
Switching node of Channel A - connect an inductor between this pin and the output capacitor.
Channel A. Ground connection for converter power stage and internal circuitry.
Channel B. Ground connection for converter power stage and internal circuitry.
Channel B. Control bit 3 - see Table 1 for decoding. This pin has a 1 MΩ internal pulldown resistor. This resis-
tor is switched in circuit whenever the pin voltage is below the input high threshold, or when the part is in
undervoltage lockout.
Channel B. Control bit 2 - see Table 1 for decoding. This pin has a 1 MΩ internal pulldown resistor. This resis-
tor is switched in circuit whenever the pin voltage is below the input high threshold, or when the part is in
undervoltage lockout.
Channel B. Control bit 1 - see Table 1 for decoding. This pin has a 1 MΩ internal pulldown resistor. This resis-
tor is switched in circuit whenever the pin voltage is below the input high threshold, or when the part is in
undervoltage lockout.
Channel B. Control bit 0 - see Table 1 for decoding. This pin has a 1 MΩ internal pulldown resistor. This resis-
tor is switched in circuit whenever the pin voltage is below the input high threshold, or when the part is in
undervoltage lockout.
Output voltage sense pin of Channel B.
Channel B. Input supply voltage for the converter power stage and internal circuitry.
Switching node of Channel B - connect an inductor between this pin and the output capacitor.
