APPLICATION HINTS

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 components

and the IC. In particular, when an external component is connected to VOUT Pin, make minimum connection

with the capacitor.

Make sufficient grounding. A large current flows through VSS Pin by switching. When the impedance of the

VSS 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 tantalum

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 generated 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 ILX 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.
