HMDVR parandus

Post by Teet »

Tervitus.
Sain lollusega hakkama ja lasin kogemata 12v peale oma tutikale HMDVR`le mis mõistagi kannatab vaid 5v. Väliste tunnuste järgi tundub vaid üks kolmejalgne komponent ära kõrbenud aga seda ei tea paljud veel kuid mõtlesin et võiks proovida parandada. Küsimus et kas keegi teab mis komponendiga võiks tegemist olla, see kolmejalgne, ehk on transistor aga milline....

See komponent on ikka viiejalgne.

see on HX 1001 GE vist

у тебя на плате стоит кондетсатор с одной стороны а с другой индукционный модуль
так что это точно степдаун конвертер напряжения к примеру входящие напряжение 5 вольт а на выходе 3.3 в
такие же коныерторы устанавливают на китайских видио регистраторах, mp3 и тд

попробуй внимательно разглядеть маркировку на камне

если там HK-NG значит точно тот камень

HK 1001 AE это уневерсальный конвертер - там выходное напряжение зависит от обвязки на ключе... стандартно он выдаёт 5.5вольт на выходе
а при обвязке 3.3 вольта

у тебя микро сд карта? тогда скорей всего 3.3вольта

Suur tänu sulle vastamast, wwdww. Müüd tean asja edasi uurida. :)

Lugesin välja. A18a oli peale kirjutatud. Arvan, et see: PWM/VFM STEP-DOWN DC/DC CONVERTER WITH SYNCHRONOUS RECTIFIER
