PRODUCTION DATA.
As the load current decreases to half the ripple current, the converter enters Power Save Mode operation. During PSM, the converter operates with reduced switching frequency maintaining high conversion efficiency. Power Save Mode is based on an adaptive peak current target, to keep output voltage ripple low. Because each pulse shifts VOUT up, a pause time happens until VOUT trips the internal VOUT_Low threshold again and the next pulse takes place.
The switching frequency in PSM (one phase operation) calculates as:
