9.3 Power Supply Recommendations

The TPS281C100 device is designed to operate in a 24-V industrial system. The allowed supply voltage range (VS pin) is 6 V to 60 V as measured at the VS pin with respect to the GND pin of the device. In this range the device meets full parametric specifications as listed in the Section 6.5 table. The device is also designed to withstand voltage transients beyond this range such as SELV supply failures.

It is recommended to place a 0.1uF capacitor at the Vs supply input to stabilize the input supply and filter out low frequency noise. The power supply must be able to withstand all transient load current steps. In cases where the power supply is slow to respond to a large transient current or large load current step, additional bulk capacitance can be required on the input.
