The BD95513MUV is a switching regulator incorporating ROHM’s proprietary H Reg

3 TM
Technical Note
CONTROLLA control system.
Light Load Mode (SLLM ) controller, further improving system efficiency.
When V OUT drops suddenly due to changes in load, the system quickly restores the output voltage by extending the t on time
interval. This improves the regulator ’s transient response. When light-load mode is activated, the IC employs the Simple

When V OUT drops due to a sudden change in load and the
voltage remains below V REF after the preprogrammed t ON time
interval has elapsed, the system quickly restores V OUT by
extending the t ON time, thereby improving transient response.

If V FB falls below V REF again, the high gate is switched back on,
lowering the switching frequency of the regulator and yielding
higher efficiency when powering light loads.

QLLM mode is enabled by setting the MODE pin to HiZ or
middle voltage. When the lower gate is off and the current
through the inductor is 0 (current flowing from V OUT to SW),
QLLM mode is activated, disabling high gate output.
If V FB falls below V REF within a programmed time interval
(typ. 40 μs), the high gate is switched on, but if V FB does not fall
below V REF , the lower gate is forced on, dropping V FB and
switching the high gate back on.
The minimum switching frequency is set to 25 kHz (T = 40 μs),
which keeps the regulator ’s frequency from entering the audible
spectrum but yields less efficient results than SLLM TM mode.
