7.2.2.2 Schottky Diode Selection

The TPS61162A, TPS61163A 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’s reverse breakdown voltage must exceed the open LED protection voltage. ONSemi MBR0540 and NSR05F40, and Vishay MSS1P4 are recommended for the TPS61162A, TPS61163A.
