5. Output Diode Selection (D)
100-kHz CURRENT-MODE SIMPLE STEP-UP/FLYBACK SWITCHING REGULATOR
SLVS633 – OCTOBER 2006
In the step-up regulator, the switching diode must withstand a reverse voltage and be able to conduct the peak
output current of the TL3577. Therefore, a suitable diode must have a minimum reverse breakdown voltage
greater than the circuit output voltage and should also be rated for average and peak current greater than
ILOAD(max) and ID(pk). Because of their low forward-voltage drop (and higher regulator efficiencies), Schottky
barrier diodes often are used in switching regulators. Refer to Table 4 for recommended part numbers and
voltage ratings of 1-A and 3-A diodes.
