Figure 10. LCM selected, 50 mA load
If an external clock is applied on the LNM/LCM pin, the L7983 switching activity is synchronized to the applied
clock and the LNM operation is enabled. The external clock must meet the electrical requirements summarized in
Table 7. In case no external clock is detected on LNM/LCM for TLNM/LCM (14 µs typ.), the free running clock
programmed on pin FSW through RFSW resistor is restored as switching frequency. Refer to
Section 5.3 Switching frequency programming and dithering.
TLNM/LCM is also the typical delay between LNM to LCM and the opposite transition.
