NOTES ON USE
1. Take ample care to ensure that none of the IC's, nor the external component's, absolute maximum ratings are
exceeded.
2. Be extremely careful when selecting parts and do not limit your reference to the specifications and characteristics for
the DC/DC converter alone. The IC also depends, to a great extent, upon the external components.
3. Arrange the peripherals in the environs of the IC. In order to reduce wiring impedance, use short, thick wires. In
particular, wire the load capacitor as close as possible and strengthen the ground wiring sufficiently.
4. Ground current during switching may cause the IC's operations to become unstable due to changes in ground voltage,
so please strengthen the IC's GND pin surroundings.

External Components
1.Setting soft-start time
In oder to lengthen soft-start time we recommend that you use the C or D types of the series which have soft start
time externally set-up.
Soft-start time (T
SS
) is between MIN & MAX, as indicated in the graphs below, so please select soft-start capacitor
value (C
SS
) to suit your application.
2. R
FB1
, C
FB
set up
fzfb = 1
÷
( 2
π
x C
FB
x R
FB1
)
In order to achieve a value for fzfb within the range of 0.1kHz to 20kHz, we recommend that values for R
FB1
& C
FB
are selected from the area indicated within the lines of fzfb = 0.1kHz and fzfb = 20 kHz as shown on the graph
below. Please select combinations of values as close to the fzfb = 10kHz line as possible.
