Selecting External Components
1. Inductor L
1
1) It must be suited for switching regulators.
Do not use inductors as noise filters as they generate excessive heat.
2) It must have the appropriate inductance value.
If the inductance is too small (150
μ
H or lower), abnormal oscillation may occur causing operation problems in the overcurrent protection
circuit within the rated current range.
3) The rated current must be satisfied.
If the rated current is exceeded, magnetic saturation leads to overcurrent.
2. Capacitors C
1
and C
2
1) They must satisfy the withstand voltage and allowable ripple current.
Exceeding the ratings of these capacitors or using them without derating shortens their service lives and may also cause abnormal
oscillation of the IC.
2) C
2
must be a low-impedance type capacitor.
A low-impedance type capacitor is recommended for C
2
to ensure minimum ripple voltage and stable switching operation.
3. Diode D
1
The Sanken AK06 diode is recommended for D
1
. If you intended to use an equivalent diode, be sure to use a Schottky Barrier diode and make
sure that the reverse voltage applied to terminal 2 of the IC does not exceed the value (–1V) given in the absolute maximum ratings. If you use
a fast recovery diode or any other diode, application of a reverse voltage generated from the recovery or ON voltage of the diode may damage
the IC.
Application
Variable output voltage
Output voltage can be adjusted in the same way as SI-8000S in page 85.
The efficiency depends on the input voltage and the out-
put current. Thus, obtain the value from the efficiency
graph on page 79 and substitute the percentage in the
formula above.
