PRODUCTION DATA.
To ensure stable operation of the charger including the power path, a list of components and their recommended value is given in Table 7. These values represent the capacitance or inductance value in the application under the given operating conditions. For example, ceramic capacitors will typically show a drop in capacitance when a DC voltage is applied. Due to this dc bias effect, the capacitance in the applications when voltage is applied is much less than the nominal capacitor value. See the capacitor manufacturer data sheet for derating.
At pin AC, a series inductance of may be used with a values as stated in Table 7.
Pins AC, SYS and BAT have been tested to be stable with the values given in Table 7:
| PIN NAME | Cmin (μF) | Cmax (μF) | Lmin (μH) | lmax (μH) |
|---|---|---|---|---|
| AC | 0.1 | 1 | 0 | 2 |
| SYS | 1 | 10 | — | — |
| BAT | 0.1 | 4.7 | — | — |
