12 Power Supply Recommendations

The TPS2660x eFuse is designed for the supply voltage range of 4.2 V ≤ VIN ≤ 60 V. If the input supply is located more than a few inches from the device, an input ceramic bypass capacitor higher than 0.1 μF is recommended. Power supply must be rated higher than the current limit set to avoid voltage droops during overcurrent and short circuit conditions.
