LS03-05BxxS(-F) 2013.09.04-A/3 Page 4 of 5 EMC RECOMMENDED CIRCUIT PCB LAYOUT (figure 4):EMC application circuit PCB layout Safety and recommend wiring: linewidth ≥3mm, line-line distance≥6mm, line-ground distance≥6mm, external components between primary circuit and secondary circuit ≥6.4mm. Module required dispensing fixed after assembled EXTERNAL CIRCUIT PARAMETERS Output Voltage C1 C2 C3 FUSE CY TVS 3.3V 10 µF/400V 1 µF/50V (Ceramic capacitor) 150 µF/25V 1A/250V 1nF/400VAC SMBJ7.0A 5V 9V SMBJ12A 12V SMBJ20A 15V 100 µF/35V 24V SMBJ30A Note: 1. C1:AC input, is filtering electrolytic capacitor (which is required), when input voltage is below 100VAC, and the value of C1 is 22 μF/400V. DC input, is a filtering capacitor in EMC Filter, the value of C1 is 10 µF/400V(when input voltage is above 370VDC, and the value of C1 is 10µF/450V), If EMC performance is not required,C1 could not need. 2. C2 is ceramic capacitor, it is used to filter high frequency noise. Output filtering capacitor C3 (which is required when AC input or DC input) is recommended to use high frequency and low impedance electrolytic capacitors. For capacitance and current of capacitor please refer to manufacture ’s datasheet. Voltage derating of capacitor should be 80% or above. TVS is a recommended component to protect post-circuits (if converter fails). External input NTC model is recommended to use 5D-9. External input MOV model is recommended to use S14K350. 3. For standard EMC requirement, please refer to figure 1.If higher EMC requirement ,please refer to figure 3, recommended parameters are shown in the table below. Recommend Parameter For Higher EMC Standard Circuit Components Recommend Parameter MOV2 S10K300 CY1, CY2 1nF/400VAC CX 0.1 µF/275VAC LCM 3.5mH LDM 5mH FC-L01DV1 MORNSUN ’s 1KV/2KV Surge protector FUSE 1A/250V, slow blow, it must be connected to FUSE LS03 DIMENSIONS, RECOMMENDED FOOTPRINT&PACKAGING |
