The VOUT_COMMAND command sets the output voltage in volts. The exponent is set be VOUT_MODE at –9 (equivalent of 1.9531 mV/LSB). The programmed VOUT is computed as:
The support range for TPS549B22 is: 0.5996 V to 1.1992 V. It is effectively 9 bits limited to 307 to 614 decimal. Slew-rate control is provided through MODE pin.
VOUT changes 1 step per tslew, where tslew is programmable by MODE pin: 4, 8, 16, or 32 μs.
