How to learn the SMD 6 Pins Power IC Lots of the new LED TV and Monitor is using the SMD 6 pins Power Supply IC. This Power IC size is small like a normal SMD transistor! Sometime we can't find where this power IC location. But sure that for the season repairer they will knew that is power IC. But that's not mean they know what's their power IC part number! So It is important to learn this information when repair the latest LCD & LED TV or monitor. Below is the location of power IC (U7001) for Sharp LC-32LE340M LED TV: http://lcd-televisionrepair.com/newsletter/LCD_&_LED_TV_Monitor_6_Pins_SMD_Power_IC.html

The Power IC body size looks like smaller than the SMD zener diode Z7007! This power IC marking code is IDP-606, did you guess what's the IC part number is? The answer is........

=> R7731AGE ! Below is the proof:

We must refer to their product specification manual to confirm that this 6 pins Power IC IDP is a R7731A.

Other 6 pins power supply SMD IC: 1) OB2263 = 63xxx

2) LD7535 = WP/35, xP/35 (subst. for OB2263 & PL3563 from aliexpress info )

3) Other 6 pins SMD Power IC: FAN6862 = ABx LD7550IL_BL = xxP/50 OB2252 = 52xxx OB2262 = 62xxx OB2273 = 73xxx SG6858TZ = AAIxx UC3863G_L = U863

Another 6 Pin SMD IC in LED & LCD TV/Monitor

Nowadays, lots of the SMD components inside the LED & LCD TV or Monitor. Especially the 6 pins type SMD components. Because of their body size is same as other three pins type SMD components, so we will think it was a diode, transistor, or etc. So with this article, I will let you know the 6 pins type SMD IC in LED/LCD TV. Here is the list of 6 pins SMD components: 1) AP4313(Constant Voltage and Constant Current Controller IC) Marking Code= G6G

2) FDC6333C(30V N & P-Channel PowerTrench MOSFETs) Marking Code= 333x => 333, 3333, 333A, 333J, 333K, 333L & etc

3) LD7537(PWM Controller Power IC) Marking Code= 37x => JtP 37R, KGP 37R, LIP 37R, LWP 37R & etc

LD7537_LEADTREND

4) NCP1251A(PWM Controller Power IC) Marking Code= 5AAxxx => 5AARBQ, 5AARCH, 5AARXN, 5AARYM, 5AARZF, 5AARZG, 5AARZH, & etc

5) NCP1251B(PWM Controller Power IC) Marking Code= 5A2xxx => 5A2RAW, 5A2RXG, 5A2RYM, 5A2RYU, 5A2RZV, 5A2RZY & etc

6) RT9293BGJ6 (High Performance Asynchronies Boots for 10 WLED Driver) Marking Code= BT=xxx => BT=904, BT=K45, BT=MO7, BT=EON, BT=FOJ & etc

7) SG6848TZ1 (Green-Mode PWM Controller Power IC) Marking Code= AAHxx => AAHBB, AAHBH & etc *Can use the EA514 marking code IC as an equivalent.

Conclusion: With the above information, you will get some points there. For example, when you see the 6 pins component marking code as: BT=xxx , it was a RichTek RT9293 Asynchronies Boots Driver IC. So that you can search their IC datasheet

with this part number and find out their valuable info to repair the TV. Or find the equivalent 6 pins SMD components in the junk board with similar marking code and replace it. Some repairer they can’t find these type of components datasheet is because, if you’re just type in their marking code in internet search engine, it can’t find any related information for you. After that it will disturb your repair jobs or even give up to repair the TV!
