Overload protection circuit
Types are selectable the S-8520/8521 Series with the overload protection circuit (A, C and E types) or without
the overload protection circuit (B, D and F types).
By the S-8520/8521 Series with the overload protection circuit (A, C and E types), the switching components
and inductor can be protected because the overload protection circuit works and is set to the intermittent mode,
in case of overload or load short-circuit.
But in case of supplying current to load by using 100% duty cycle, select the S-8520/8521 Series without the
overload protection circuit (B, D and F types), according to the conditions of application.
The operation voltage differs in 10 V (A, B and E types) or 16 V (B, D and F types) whether the overload
protection circuit is available or not.
Table 9 shows items for selecting the type according to the requirements of application. Select it matching the
marks ( ) for your requirement.

The need of overload protection circuit
Input voltage exceeds 10 V
Focusing on efficiency of light load status
(1 mA or less)
Using with middle load current (about 200
mA)
Using with large load current (about 1 A)
Focusing on the low ripple voltage
Focusing on downsizing external parts
Remark
: Indispensable condition
: Superiority of requirement
: Particularly superiority of requirement
