7.3.6 Operating Range
The TPSM84209 operates over a wide input voltage and output voltage range; however, not all output voltages can operate over the entire input voltage range. The maximum and minimum input voltage limits are shown in Figure 20. The TPSM84209 can be operated between the Maximum and Minimum VIN limit lines.
Operating above the Maximum VIN line may cause the device to skip pulses in order to maintain the regulated output voltage.
