JAJSMQ0D October 2022 – September 2023 TPS61033 , TPS610333
PRODUCTION DATA
There are two ways to set the output voltage of the TPS61033: adjustable or fixed. If the FB is connected to VIN, the TPS61033 works as a fixed 5.0-V output voltage version, the TPS61033 uses the internal resistor divider.
The output voltage is also can be set by an external resistor divider (R1, R2 in Figure 9-1). When the output voltage is regulated, the typical voltage at the FB pin is VREF. Thus the resistor divider is determined by Equation 5.
where
TPS610333 can only support fixed 5.0-V output voltage, so FB should be connected with VIN rather than external resistor divider.
