10. Instructions for pattern layouts
(1) In order to stabilize VIN voltage level, we recommend that a by-pass capacitor (CIN) be connected as close as possible to the
VIN and GND pins.
(2) Please mount each external component as close to the IC as possible.
(3) Wire external components as close to the IC as possible and use thick, short connecting traces to reduce the circuit impedance.
(4) Make sure that the GND traces are as thick as possible, as variations in ground potential caused by high ground currents at
the time of switching may result in instability of the IC.
(5) Internal driver transistors bring on heat because of the output current (IOUT) and ON resistance of the Nch MOS driver transistors.
