• Manufacturer Part Number: sc4524a
• Description: Sc4524a 28v 2a Step-down Switching Regulator
• Manufacturer: Semtech Corporation

Table 4 lists the recommended inductance (L
voltages. The inductance is determined by assuming that the ripple current is 35% of load current I
parameters are calculated by assuming a 22mF low ESR ceramic output capacitor and a loop gain crossover frequency
of F
