TPS40170: Swing of Vout from 3V to 26V

ACGUY

Part Number: TPS40170

Hello E2E,

I want to do swing the Vout any by MCU settings. TPS40170 has TRK pin. If bias input to TRK-pin from MCU's DAC-output, does Vout to be variation?
Is this usage common?

Hi ACGUY,

If TRK pin is smaller than reference, Vout variation is decided by MCU DAC output variation and feedback resistor variation. You can do like this.
