ZHCSO00A March 2022 – March 2023 TPS629211-Q1
PRODUCTION DATA
The output voltage of the TPS629211-Q1 is adjustable and 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 Table 9-2. TI recommends to size R2 to be less than 300 kΩ to allow for a feedback current of at least 2 μA. Lower resistor values are recommended for highest accuracy and most robust design.
