PRODUCTION DATA
In FPWM mode, frequency is maintained while lightly loaded. To maintain frequency, a limited reverse current is allowed to flow through the inductor. Reverse current is limited by reverse current limit circuitry, see Electrical Characteristics for reverse current limit values.
For all devices, in FPWM mode, frequency reduction is still available if output voltage is high enough to command minimum on time even while lightly loaded, allowing good behavior during faults which involve output being pulled up.
