7.2.2.2 Schottky Diode Selection

The TPS61169 demands a low forward voltage, high-speed and low capacitance Schottky diode for optimum efficiency. Ensure that the diode average and peak current rating exceeds the average output current and peak inductor current. In addition, the diode reverse breakdown voltage must exceed the open LED protection voltage. ONSemi NSR0240 is recommended for the TPS61169.
