This is the built-in FET of drain terminal. The primary coil minus side of the external transformer, and the snubber circuit for noise reduction are connected to this. Be sure to evaluate it under the condition that it C1: Capacitor for input voltage smoothing 10µF/450V is mounted by your product. Especially, confirm C2: For noise terminal voltage reduction 2200pF/1kV whether output power never exceeds a maximum standard with current probe. C3: Capacitor for Vod voltage smoothing 10µF/50V C4: Capacitor for output voltage smoothing 1000µF/25V C5: For noise terminal voltage reduction 2200pF/AC250V C6: Noise terminal voltage Please set it, if necessary countermeasure capacitor Limiting element voltage DC630V or higher 0.1 to 0.22µF D1: Rectifier diode FRD 800V/0.5A D2: Rectifier diode FRD 200V/1A D3: Diode bridge 800V/1A R1, R3: Resistor 360kΩ±5% 0.25W R2: Resistor 200kΩ±5% 1W R4: Bleeder resistor In case Io is less than 10mA, connect a bleeder resistance in parallel to C4. T1: Switching transformer FL1: For noise terminal voltage reduction Please set it, if necessary FUSE: Fuse Be sure to use this for safety. ZNR: Varistor Must be use. It protects this part from lightning surge and static electricity. Precautions on use of products When the capacity of the output smoothing electrolytic capacitor C1 is made large, output may not rise. 100µF to 2200µF is recommended. Set the rise time within 10ms. Set the Vod electrolytic capacitor C3 to 10µF. Be sure to use the VG terminal voltage within the operating voltage range. Set the external starting resistor (R1+R3) to 720KΩ. When reducing the resistance value, start-up may fail. Take note of the loss of the resistor when it is reduced. This product has built-in over current (reset type) protection function to prevent destruction at abrupt error. These protection functions are effective for prevention against destruction owing to abrupt accident, therefore, avoid using them for continuous protection circuit operating, or at transition Conversion Efficiency Conversion Efficiency η (%) Be sure to use fuse for safety. <In case of 12V output> (Vin=311V, Ta=25°C) 100 80 60 40 20 0 0 50 100 150 100 250 300 350 400 450 500 Output Current Io(mA) Load Regulation <In case of 12V output> (Vin=311V, Ta=25°C) Output Voltage Vo(V) Sample Application Circuit 18.0 16.0 14.0 12.0 10.0 8.0 6.0 4.0 2.0 0.0 Maximum Io=500mA 0 200 400 600 800 1000 Output Current Io(mA) 1200 Appendix Notes No technical content pages of this document may be reproduced in any form or transmitted by any means without prior permission of ROHM CO.,LTD.
