Описание: Working of 3V 5V Buck Regulator | stepdown | Buck convertor | PWM | rt8205a | Laptian Institute Pune

In this video, I have explained how the PWM BUCK REGULATOR RT 8205 IC works internally on a laptop motherboard, what exactly PWM CONTROLLER is, and how 3v 5v stepdown or buck regulator functions.

In addition, this video also explains about ENTRIP, PHASE, TONSELECT, VFB, REF, UGATE, LGATE, VOUT, VOLTAGE FOLLOWER, ZERO DETECTOR, CURRENT LIMIT, PGOOD, AND GATE, OR GATE, NOT GARE, REF VOLTAGE.

If SMPS buck regulator or 3V 5V standby section does not work, then I/O will also stop functioning. This situation occurs particularly because IO, EC_ON, S5_ON, MAIN_ON, SUS_ON signal is generated only when it receives 3v supply.
An in-depth understanding of basic components, schematic diagrams, circuit calculations, power sequence concepts is really important to carry out laptop motherboard repair. Laptop repair becomes quite easy when you know how a motherboard supply flows and how an IC functions internally.

At Dr. Lapcare, you will also get the complete workshop training upon the successful completion of the course, where you will have to perform live laptop repair.
