When using these ICs, be sure to take care of the following points:
Set external components as close as possible to the IC and minimize the connection between the compo-
nents and the IC. In particular, when an external component is connected to V
OUT
Pin, make minimum con-
nection with the capacitor.
Make sufficient grounding. A large current flows through V
SS
Pin by switching. When the impedance of the
V
SS
connection is high, the potential within the IC is varied by the switching current. This may result in
unstable operation of the IC.
Use capacitor with a capacity of 10μF or more, and with good high frequency characteristics such as tanta-
lum capacitor. We recommend the use of a capacitor with an allowable voltage which is at least three times
the output set voltage. This is because there may be the case where a spike-shaped high voltage is generat-
ed by the inductor when Lx transistor is turned off.
Take the utmost care when choosing a inductor. Namely, choose such an inductor that has sufficiently small
d.c. resistance and large allowable current, and hardly reaches magnetic saturation. When the inductance
value of the inductor is small, there may be the case where I
LX
exceeds the absolute maximum ratings at the
maximum load. Use an inductor with an appropriate inductance.
Use a diode of a Schottky type with high switching speed, and also take care of the rated current.
The performance of power source circuits using these ICs largely depends upon the peripheral components. Take
the utmost care in the selection of the peripheral components. In particular, design the peripheral circuits in such a
manner that the values such as voltage, current and power of each component, PCB patterns and the IC do not
exceed their respective rated values.
