PRODUCTION DATA
The VCC pin is the output of the internal LDO subregulator used to supply the control circuits of the converter. Connect a 1-μF, 16-V ceramic capacitor from VCC to AGND for proper operation. In general, avoid loading VCC with any external circuitry. However, VCC can be used as the pullup supply for the PGOOD indicator – a 100-kΩ pullup resistor is a good choice in this case. Note that VCC remains high when VEN-WAKE < VEN < VEN-TH. The nominal VCC voltage is 3.3 V. Do not short VCC to ground or connect to an external voltage.
