ZHCSQD3A october 2022 – march 2023 TPS62992-Q1
PRODUCTION DATA
When the MODE/S_CONF pin is configured for external feedback, the output voltage of the TPS62992-Q1 is fully 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 11. TI recommends 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:
