Figure 6. A Well Chosen Input Network Prevents Input Voltage Overshoot and Ensures Reliable
Operation When the LTM8023 is Connected to a Live Supply
ripple filtering and can slightly improve the efficiency of the
circuit, though it is likely to be the largest component in the
circuit. An alternative solution is shown in Figure 6c. A 0.7?
resistor is added in series with the input to eliminate the
voltage overshoot (it also reduces the peak input current).
A 0.1μF capacitor improves high frequency filtering. This
solution is smaller and less expensive than the electrolytic
capacitor. For high input voltages its impact on efficiency
is minor, reducing efficiency less than one-half percent
for a 5V output at full load operating from 24V.
