Functional description

5.5

Light-load operation

The MLF pinstrapping during the power-up phase determines the light-load operation (refer

to Table 7 on page 11, Table 8 and Table 9 on page 12).

5.5.1

Low noise mode (LNM)

The low noise mode implements a forced PWM operation over the different loading

conditions. The LNM features a constant switching frequency to minimize the noise in the

final application and a constant voltage ripple at fixed VIN. The regulator in steady loading

condition never skip pulses and it operates in continuous conduction mode (CCM) over the

different loading conditions.

Figure 13. Low noise mode operation

Typical applications for the LNM operation are car audio, sensors.
