Note 1: When not using the ON/OFF control, keep ON/OFF pin open.
Note 2: When not adjusting output, keep V.ADJ pin open.
Note 3: When it includes inductance in input line or switch ing element is connected to the input side or the wire is long,
to fulfill the performance C1 will be required. Also to lower the input impedance we recommend a pattern that has an
additional C1, and to verify on a actual equipment. Or, by adding C2 you can lower the output ripple more.
Recommended Capacitor
C1=33 µF10WV
C2=2.2 µF~22µF
C2: An output capacitor is built-in so it is not required, however by connecting 2.2 µF~22 µF you can lower the noise more
Note 4: There is no +S, Pin in TSI 20N-0510V SIP type.
Method of Adjusting Output Voltage
When using at 3.3V without adjusting output voltage, keep V.ADJ pin (12Pin) open.
By connecting a resistor between +Vout pin (9~11Pin)~V.ADJ pin (12Pin), you can adjust the output voltage in the range of 0.8~3.3V.
(Vout Down Control)
By connecting a resistor between Vadj pin (12Pin)~GND pin (5~8Pin), you can adjust the output voltage in the range of 3.3V~3.6V.
(Vout Up Control)
To calculate external resistance, please refer to the equation below. After calculating external resistance, please check output voltage
and adjust resistance value.

Remote ON/OFF Control
- ON/OFF Function
By using this ON/OFF control function, the output can be ON/OFF controlled without intermitting input.
This is an effective function when composing a power supply system sequence. And this can also be used as a power standby function for
saving power control.

To not use the ON/OFF function, keep ON/OFF pin open.

Method to decrease noise
Usually TSI 20N series is used adding an input/output capacitor,
and making the most of the converter's performance and to decrease
the noise more, consider the following items when designing the
print board.

- This product has a built-in over-current, short protection, but
long time of short circuit will cause failure, so please avoid that.
- May not be used in a use of that would affect lives or properties
directly by the failure of this product. Please confrim before adopting.
- Product can not be used under oscillation, strike or temp. condition
that are out of the specification. Contact for any questions.
- There is possibility of damage from static. When the worker has
electrified static, electrical discharge by grounding, and recommend
working on a table grounded.

- This product does not have a built-in fuse. Connect a huse to the
+input line for protection when over-current flows into input at
abnormal. Please be sure that the supplying power has the capacity
to cut the fuse.
Evaluation
Should be nothing extraordinary in electrilcal characteristics and appearance
before or after the test.
- This product does not have a built-in over-voltage protection. When
over-voltage occurs by the abnormality in the module there is a mode
that input voltage comes out at output as it is, and this may cause
smoke and ignition. To prevent this, be sure to add over-voltage protection.
- There is no test result report attached for this product.
