LD7904 PWM Power IC DIP-6

The LD7904JGP7  is a PWM (Pulse Width Modulation) Power Controller IC mainly used in SMPS (Switch Mode Power Supply) circuits.

👉 This IC controls the switching of power MOSFETs to regulate output voltage efficiently.
👉 If your LED TV, power adapter, or SMPS board is dead or not starting, this IC is often one of the main faulty components.

💡 In simple words:
It acts like the “brain” of the power supply, controlling how electricity flows and ensuring stable output.
