Series Operation Choose a diode in accordance with voltage, power dissipation and heat radiation. - Voltage : V ＞ Vo × 3 - Current : I ＞ Io × 3 - Design a proper heat sink according to power loss at diode ( Pw = Vf × Io ). - Use a schottky or fast recovery diode this has a low VF. NOTE: To avoid excessive voltage drop and for improved noise, and short and thick wire should be used to connect the load. Length below 50Cm & wire thickness of 4.0A/mm2 are recommended for reducing wire loss when wire connection is necessary. 2. Parallel Operation 4. Over Current Protection This supply can be operated the following ways. Choose a diode in accordance with voltage, power dissipation and heat radiation. - Voltage : V ＞ Vo × 3 - Current : I ＞ Io × 3 - Design a proper heat sink according to power loss at diode ( Pw = VF × Io ) - Use a schottky or fast recovery diode this has a low VF. Output current is grown, this is mainly due to the poor coupling between the auxiliary winding and the power winding. Which prevents proper collapsing. When Vout goes low.

Withstand Voltage SFS5 series are designed to withstand 3KVAC (10mA) 1 minute between input output for the withstand voltage test, the applied voltage must be increased gradually from zero to the testing value, and then decreased gradually at shut down. Especially stay away from use of a timer. Where a pulse of several times the applied voltage can be generated. 11. No-Load Power Consumption No-Load power is the energy used by a device when it is disconnected from it's load and performing no function. 12. Short Circuit Protection 5. Over Voltage Protection SFS series are equipped with an over-voltage protection circuit by zener diode. If zener diode is opened, Vcc rise up, it becomes possible to implement an over voltage protection. Ratch on mode. If zener diode is short, output is shorted. It becomes possible to implement a short circuit Protection. 6. Over Temperature Protection Temperature protection is provided by a precision analog circuit that turns the output MOSFET off when the junction temperature exceeds the thermal shutdown temperature (130℃ Min. , 140℃ Typ. and 70℃ hysteresis). When the junction temperature cools to below the hysteretic temperature, normal operation resumes providing automatic recovery. 7. Line Regulation Maximum line regulation is maximum output voltage change when the input volt is slowly varied with in the input voltage range. 8. Load Regulation Maximum load regulation is maximum output voltage value change when varying the load current slowly within the standard output current range. 9. Isolation Resistance The isolation resistance is more than 100MΩ at

500 VDC when tested with DC isolation between the

output and the case. Make sure that during testing, the isolation tester does not produce a high pulse when the applied voltage is varied. Ensure that the tester is fully discharged after the test. By permanently monitoring the feedback line activity, the IC is able to detect the presence of a short-circuit. Immediately reducing the output power for a total system protection. Once the short has disappeared, the controller resumes and goes back to normal operation. L N G N D O utput
