Example of Over-voltage Protection Circuit. Generally, in constant-voltage power supply circuit, output voltage will become higher than the specified value (over-voltage state) in case of any failures or PC board solderability defects. To minimize the damage caused by this over-voltage, we recommend setting an over-voltage protection circuit. In designing, the following confirmations are necessary in actual circuit. 1) How the over-voltage protection circuit operates and its effects. 2) Is there any malfunction due to ambient temperature change of each device or exogenous noises?

Example of Over-voltage Protection Circuit. The thyristor will operate when it accept an over-voltage (VOUT) signal, then the fuse is melted and the input power is cut off, then the operation of IC1 is stopped.

SS terminal (5 pin) also acts as standby mode switch. By setting SS terminal (5 pin) voltage to be equal or less than 0.3Vtyp, the output ON/OFF is able to be controlled by external signals. ON/OFF Control Circuit Example

In addition, confirmation of the following points is necessary in actual circuit. 1) How the output ON/OFF control operates and its effects. 2) Is there any malfunction due to the ambient temperature change of each device or exogenous noises?
Points to Remember in Pattern Designing 1) Transient large current flows to VIN terminal (1 pin), so we recommend the input capacitor should be 3000F and above. In addition, (+) (-) terminals of the input capacitor should be set near to VIN terminal (1 pin) and GND terminal (2 pin). 2) Large current flows to C1A to C, VIN terminal (1 pin) of IC1, SWOUT terminal (3 pin), D1, L1, and C2A. So, the wiring should be thick and short. 3) FB terminal (4 pin) of IC1 is the feedback terminal from output voltage. It should be near to the output capacitor C2A. * For the purpose of ensuring the stability of oscillation, a capacitor should be inserted between SS terminal (5 pin) and GND terminal (2 pin). * The absolute maximum rated voltage of SS terminal (5 pin) is 7V. The absolute maximum rated voltage of FB terminal (4 pin) is within the range of 5 to 30V according to the output voltage type. When a voltage equal or higher than the rated value is applied to SS terminal (5 pin) or FB terminal (4 pin) in some cases such a abnormal test, protection measures like inserting fuses should be taken. * The built-in over-heat protection is a function to prevent the circuit from overheat state caused by transient temperature rise, but not a function to prevent from abnormal caused by a sudden heat generation. In addition, the reliability of over-heat protection function is not guarantee.
