Figure 26. 3.3-V Power Supply With Schottky Diode
Figure 26 shows an application where a clamp diode is
used in place of the low-side FET. The TPS54352−7
incorporates an integrated pull-down FET so that the
circuit remains operating in continuous mode during light
load operation. A 3-A, 40-V Schottky diode such as the
Motorola MBRS340T3 or equivalent is recommended.
See Figures 15−17 for efficiency data and switching
waveforms for this circuit.
