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.
