SLVSER3A November 2018 – April 2020 TPS65982BB
PRODUCTION DATA.
The VIN_3V3 input is the main supply to the TPS65982BB device. The VIN_3V3 switch (S1 in Figure 13) is a unidirectional switch from VIN_3V3 to LDO_3V3, not allowing current to flow backwards from LDO_3V3 to VIN_3V3. This switch is on when 3.3 V is available. See Table 4 for the recommended external capacitance on the VIN_3V3 pin.
