INN2124K, INN2125K-TL, INN2004K-TL, and INN2003K-TL are all Power Integrations InnoSwitch-series offline flyback switcher ICs in the same 16-PowerSOIC / eSOP package family. INN2124K and INN2125K-TL are closer alternatives within the InnoSwitch-CE family, both intended for compact isolated CV/CC flyback power supply designs with integrated 650V MOSFET technology. INN2124K is suitable for 15W-class applications, while INN2125K-TL may be selected when a higher power/current design margin is required.
INN2004K-TL and INN2003K-TL are earlier or related InnoSwitch variants and should be compared carefully by output power, current limit, reference design, package suffix, and BOM compatibility before substitution. For new designs, choose the part according to required output power, thermal margin, switching performance, and availability; for replacement use, verify the exact suffix, PCB footprint, and datasheet parameters before purchase.
