1.What is the difference between TD1018 and EL1018?
The coupler energy is perfectly aligned with the EL1018 and has the same CTR value. Optocoupler applications are very wide, in communications, industrial, consumer electronics and other fields have applications, such as the market 18W USB PD Fast Charger, need to use the transistor output of optocoupler, the main function is to span between the primary and secondary, for the primary secondary communication, for feedback regulation of the output voltage.
Â
2.What are the functions of this optocoupler and what are the areas of common use?
Taking TD1018/1019 as an example, the device integrates an infrared light-emitting diode, a phototransistor detector and a 4-pin LSOP package. Used in Charger, for primary and secondary circuit communication, feedback regulation output voltage. It can be applied to the signal transmission between programmable controller, measuring instrument, telecommunication equipment, household appliances, different potential impedance circuits, etc.
Â
3.TD1018 Optical coupling characteristics?
The TD101X series uses an aluminum gallium arsenide infrared emission diode as the emitter, which is optically coupled to a silicon plane phototransistor detector in a plastic SOP4 package with different lead formation options. The TD1018 series has a robust coplanar dual-mode substructure with stable isolation properties.
Â
4.The difference between 1018 and 1019 for direct charge?
Direct charge on the optical coupling can be used to the day electric TD1018 (T1) -GV, TD1019 (T1) -GV, TD1010 (T1) -GV model, specifications for the first optimal technology, mainly play two roles, the first is to achieve the primary and secondary isolation, the second is the output voltage control, when the output voltage rise secondary light emitting diode light strengthened, the primary photosensitive transistor current increases, shunt switch tube base current, and reduce the switch tube conduction time, reduce the output voltage. On the contrary, when the output voltage is low, the output voltage is increased by increasing the conduction time to achieve the effect of voltage regulation. Both products are TD101X series, but the CTR value is different, with CTR 130-260% for TD1018 and CTR 200-400% for TD1018. In the product design selection, pay attention to the current transmission ratio.
Â
5.What are the widely used optical coupling on mobile phone fast charging?
TD1018 The optical coupling distance is 2.54mm, which is widely used in mobile phone fast charging, household appliances, such as fan heaters, telecommunication equipment, hybrid substrate requiring high density installation, and signal transmission between different potentials and impedance circuits.
1. Urrent transmission ratio: (current transformer: 50~600% at If = 5 mA, Vce = 5 V)
2. High input / output isolation voltage (Viso = 5000 VRMS)
3. Creepage distance is> 8mm
4. Long mini flat package: 2.3mm profile
5. UL / CUL approval: E236324
6. Approved VDE: 40007240
7. CQC approval: CQC18001204187
8. This product does not contain limiting substances and meets the RoHS standard
The parameters introduced above are that more TD1018 models are used in mobile phone fast charging, which belong to TD101X series. There are different from different line requirements. Not only this optical coupling is popular, but also its TD1019 optical coupling is used for fast charging series.
