10 Power Supply Recommendations

The TPS62590-Q1 device is designed to operate for an input voltage range from 2.5 V to 6 V. For the VIN pin, TI recommends a low ESR ceramic capacitor with a typical value of 10 μF for most applications. Capacitance derating for aging, temperature, and DC bias must be taken into account while determining the capacitor value.
