Application Circuit Example
LA5616
Note: 1. The capacitors Cn and C_RES are only needed when external noise is a problem.
If these capacitors are used, then capacitor Co must have a value at least 1/3 that of capacitor C_IN.
A certain amount of noise may occur when V_IN goes off due to differences in discharge timings between the
capacitors.
2. A capacitor with a low temperature dependence must be used for the delay capacitor Cd.
3. The minimum value for the output capacitor Co is 47 µF.
4. The input voltages must obey the relationship V_IN1 ≤ V_IN2, and must be brought up at the same time.
