Identificare circuit integrat SMD

[catalin004]

Salutare...si LA MULTI ANI!!!

 

Mi-a venit la reparat un LCD Blaupunkt, la care sursa este prajita e bara de 5V, circuitul este separat pe sursa, adica cu alt controler si FET....cod sursa

LK-OP416001A

Am schimbat componentele arse, insa tin sa schimb si integratul care comanda FET-ul, pe el scrie

36AA

004

 

si nu gasesc nimic despre el...multumesc

Identifying the manufacturers type number of an SMD device from the package code can be a difficult task. Unfortunately, each device code is not necessarily unique.
It is possible for various manufacturers to place different devices in the same case with the same SMD-code. For example, with a 6H SMD-code in a SOT-23 case might be either a npn-transistor BC818 (CDIL) or a capacitancediode FMMV2104 (Zetex) or a n-channel JFET transistor MMBF5486 (Motorla) or a pnp-digital transistor MUN2131 (Motorola) or a pnp-digital transistor UN2117 (Matsushita) or a CMOS-integrated circuit- voltage detector with reset output R3131N36EA (Ricoh). Even the same manufacturer may use the same code for different devices.
To identify a particular SMD device, is necessary to identify the manufacturer, package style and note the ID code printed on the device.
The identification of the manufacturer is possible only if on the case are printed the manufacturer’s logos, but it not always happens. Besides, sometimes it is possible to determine the manufacturer with indirect tags. Many recent Motorola devices have a small superscript letter after the device code, such as SAC (this smaller letter is merely a month of manufacture code). Siemens and Infineon devices usually have a lower case 's' (ATs, LOs). Philips devices usually have a lower case 'p' (AHp, Z1p, pB0) or '-' (D-Q, Z-S) for the devices made in Hong Kong and 't' (ZtS, tT9, Y7t) for the devices made in Malaysia. In section 5 are submitted the logos of the SMD devices manufacturers.

Se mai distinge logo-ul firmei din centrul tranzistorului?

Aici aveti conditiile de identificare a unei componente smd:trebuie sa stiti ,tipul capsulei,indicativul,producatorul componentei.

Nu se vede logo-ul....insa nu este tranzistor,este un CIP cu 3+3 pini

Se aplica aceleasi conditii,nici logoul nu se distinge?

[catalin004]

nu........

[catalin004]

Da, exact ca acela este....

Deci un pas l-am indeplinit e carcasa TSOT-23-6

Multumim frumos domnule sorin, este util atach-ul pentru viitoare "descoperiri"

004 - e indicativul tau ?

LK-OP416001A

IC1 - FAN7530 (L6562D) + Q1 - MDF12N50E PFC chip

IC2 - L6599AD + Q2 / Q3 - MDFKF5N50 alimentarea principală

IC6 - 73B12

alte tranzistoare :, Q7-JCS2N65F câmp N-ch., 2A / 650V Rds = 5ohm

* cu FDC6306P

Din pacate este 7536, insa nu este identic cu 7530/7535 pe care le-am gasit la noi....are pinul 3 cu alta functie (sleep)

Vezi sa nu fie si chooperul in scurt si atunci degeaba cumperi piesele , eu spun sa montezi o sursa de DVD pentru tensiunea de 5v si ai rezolvat problema

[catalin004]

Ma colegu da ce idee mi-ai dat....ma gandeam la un alimentator de telefon...capabil sa debiteze 1A..oricum stau degeaba prin casa....

Acum am vazut ca are 5VS si 5VSB...deci sursa de DVD este cea mai buna

Ce am gasit pe paginile din China este doar ca este "integrat de putere,driver"
