2.4 Output Schottky Diode (D4, D10) and LED Indication (D6, D12):

TI recommends Schottky diode D4 (channel 1) and D10 (channel 2) in conditions where output voltage can have negative transients that can exceed absolute maximum ratings of LM74502. The Schottky diodes can be removed if negative transients are not possible at the output.

D6, D12 provides an indication on the status of the output voltage on channel 1 and channel 2.
