This product can be effected by contacting resistor, so do not use a connector, and solder directly to the print board. Note 2. For C1, C2 approximate the converter's pin as much as possible, and wire with a bold pattern. Approximate (+) and (-) to make the loop not big. Note 3. Connect +Vs pin and -Vs pin to the capacitor closer to the load side. This pin is a remote sensing pin so do not keep it open. Remote Sensing +Vs pin and -Vs pin are remote sensing pins. The connecting point of sensing line and output line will be the output setting voltage. (Between A-B of above figure) By this function, the voltage drop at the output line can be corrected. As much as A point and B point gets closer to the load side, Vout (voltage between 7-8pin) will become higher than the output setting voltage. Adjusting Output Voltage Output voltage is adjustable in the range of 1.0~3.3V by connecting a resistor between V.ADJ1pin (11Pin) and V.ADJ2 pin (12Pin).

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. - Not using ON/OFF Function To not use the ON/OFF function, keep ON/OFF pin open. - Method of ON/OFF Control Between ON/OFF pin (1Pin) and S.GND (2Pin) Open (Max. 6V) will be generated Output=ON Short (0~0.5V 500A max.)

If there is a possibility of reverse connection, please add a protection as the left figure. The left figure is an example using huse and diode. Over-Voltage Protection TSI-40 series does not have a built-in over-voltage protection. If the switching element in this converter is damaged in short mode input voltage +Vin will be output as is. However, to prepare for damage at over-voltage mode, we recommend to add a circuit to intercept the supplying power circuit.
