22/29

input device current consumption measured at the VCC pin(IEXT5V). Both switching

sections are working in NO-AUDIBLE SKIP mode. No load is applied.

Figure 16.

Input current vs. input voltage

In the following illustrations, the device current consumption is measured in shutdown mode

and standby mode. In shutdown mode all outputs are off (SHDN pin low). In standby mode

only the linear regulator output is on (V5SW = SGND, SHDN pin high, EN5 and EN3 pins

low).
