| Identify FC2rJT step-down regulator SMD |
| (1/1) |

I have a consumer TP-LINK Archer C20 router which comes with a 9V brick and I would like to check if I can feed it with unregulated voltages up to 15v. This is the regulator circuit. Input 9V and output 3.3V. Any luck getting the part number to check the voltage specs? |

Maybe it's this one.. pinout seems to match and datasheet mentions FC2 as marking : fitipower integrated technology lnc FR8204 https://datasheet.lcsc.com/szlcsc/Fitipower-Integrated-Tech-FR8204S6CTR_C172766.pdf Low RDS(ON)Integrated Power MOSFET(170mΩ/90mΩ) Internal Compensation Function Wide Input Voltage Range: 4.5V to 18V 0.8V Reference Voltage 2AOutput Current 500kHzSwitching Frequency 1msSoft-StartTime Cycle-by-Cycle Current Limit Over-Temperature Protectionwith Auto Recovery Under Voltage Lockout Hiccup Short Circuit Protection SOT-23-6 Package |

The reference voltage is 0.8V as on that datasheet. Looks good. Thanks! |

A good way to confirm is to look at images from sellers of the part: https://detail.1688.com/offer/590026600855.html |
