JAJSPB3 November 2022 TPSM82902
PRODUCTION DATA
The output voltage of the TPSM82902 is adjustable. It can be programmed for output voltages from 0.6 V to 5.5 V using a resistor divider from VOUT to GND. The voltage at the FB pin is regulated to 600 mV. The value of the output voltage is set by the selection of the resistor divider from Equation 10. It is recommended to choose resistor values that allow a current of at least 2 μA, meaning the value of R2 must not exceed 400 kΩ. Lower resistor values are recommended for highest accuracy and most robust design.
With typical VFB = 0.6 V, 1-MHz switching frequency is not recommended for VOUT > 1.8 V.
