Hi,
I wanted to modify the input power range from 120v to 230V Panasonic cordless phone charger SMPS type, which is currently supporting only 120v AC.
I have opened the charger and tried to find the similarity with Nokia charger(100-230v), but not much information.
It has UTC MJE 13003L - High Voltage Fast-Switching NPN Power Transistor. Also other SMD component 6pin DIP but unable to find #,manufacturere details but it shows LĀBU

Fuse resistor - 10Ω
Input filter capasitor - 4.7μF 200v
Input Inductance - 470mH

Can anybody thro' some light on this.

Thanks in advance,
Mugunthµµµµ

Disappointed!
I could not find OEM charger locally.
so thought of changing the existing components to make that charger work with 230v supply.
