Not sampled.
Increased Probability of Boost Converter Entering Active Low Current Mode
The boost converter may enter and stay in Active Low Current Mode at supply voltages and
load currents higher than those specified. This is due to high switching currents in bonding
wires of the SOIC package. Devices packaged in MLF are not affected.
Problem Fix / Workaround
Add a 1.5nF capacitor between pins LSW and GND of the SOIC package. Also, increase the
value of the by-pass capacitor between pins V
Alternatively, use the device in MLF, without modifications.

and GND to at least 30µF.
