Characteristics

SI-8500L application circuit
Terminal no.2 is for soft start. Connecting a capacitor to the terminal
enables the soft start function. See page 85 for the formulas to calcu-
late delay time and rise time. Output can be turned on and off by
using the soft start terminal. To stop output, set the soft start terminal
voltage to V
SSL
(0.2V typ.) or less. To switch the potential of the soft
start terminal, drive the open collector of the transistor. Since the
discharge current from C
3
flows to the ON/OFF control transistor, limit
the current for protection. The SS terminal is pulled up to the power
supply in the IC and no external voltage can be applied.

Caution
1. Allocation of Components
For the best operating environment, the ground should be a single ground line at the GND terminal (terminal 2 on the SI-8400L, terminal 3 on
the SI-8500L), and the wiring from C
1
and C
2
to ground should be as short as possible.
2. Capacitors C
1
and C
2
1) They must satisfy the breakdown 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 to ensure minimum ripple voltage and stable switching operation.
3) C
3
(SI-8500L only) is a capacitor for soft start. When not using soft start, leave terminal 2 open. It is pulled up inside the IC.
3. Terminals LIN and NC in the connection diagram must be left unconnected to other circuits.
4. The IC's metalic heatsink is electrically floating. Do not connect it to GND or any other circuit.
5. Since the SI-8400L and 8500L series have an open-package construction, they can only be operated in specific environments. Verify the
operating environment and use the conditions indicated in the reliability data.
