moose001 Posted February 22, 2023 Report Posted February 22, 2023 Hi Can anyone identify this 6pin PWM controller? its on a (non-working) Black&Decker 18V Li-ion charger. thanks in advance. Quote
HarryA Posted February 22, 2023 Report Posted February 22, 2023 That is most likely an internal factory number. Remember they do not want you to repair them but to buy new ones. There are a number of videos on youtube in regard to chargers. Search on " Black&Decker 18V Li-ion charger " for example: https://www.youtube.com/watch?v=c-pTziUV1as Quote

moose001 Posted March 2, 2023 Author Report Posted March 2, 2023 well..actually..i was told that it is a richtek R7731A. i was directed to these sites.... http://www.smdmark.com/en-US/search/code?id=dp%3D and https://www.s-manuals.com/smd From their datasheet the marking is really idp=W where W is a date code. chopper r7731a_richtek.pdf Quote
