SLVSHL0C June 2024 – September 2024 TPSM81033
ADVANCE INFORMATION
There are two ways to set the output voltage of the TPSM81033: adjustable or fixed. If the FB is connected to VIN, the TPSM81033 works as a fixed 5.0V output voltage version, the TPSM81033 uses the internal resistor divider.
The output voltage is also can be set by an external resistor divider (R1, R2 in Figure 7-1). When the output voltage is regulated, the typical voltage at the FB pin is VREF. Thus the resistor divider is determined by Equation 2.
