9.2.2.7.1 Minimum Output Voltage
Due to the internal design of the TPS7H4001-SP, there is a minimum output voltage limit for any given input voltage. The output voltage can never be lower than the internal voltage reference of 0.604 V. Above 0.604 V, the output voltage may be limited by the minimum controllable on time. The minimum output voltage in this case is given by Equation 32.
Equation 32. 
In this equation:
- VOUTMIN is the minimum output voltage
- VINMIN is the minimum input voltage for the application
- tON,MIN is the minimum on-time for the device, for which the maximum specification is 235 ns
- fsw is the switching frequency of the application.
