The LNK625PG is a power integration IC used for off-line power supply applications. It is part of the LinkSwitch-II family, which is designed for low-power, high-efficiency applications like LED drivers and small power adapters.
The LNK625PG comes in a DIP-8 (dual in-line package) with 8 pins. The functionality of these pins is as follows:
1. BP/M (Bypass/Multi-Function Pin): Connects an external bypass capacitor to stabilize the IC’s internal bias supply.
2. D (Drain): Connects to the high voltage DC input and serves as the power switch.
3. S (Source, Pins 3, 5, and 6): These are the return path for the internal switch current and connect internally for heat dissipation.
4. FB (Feedback Input): Used for regulation, this pin senses the output voltage via an optocoupler to adjust the switching on/off.
5. NC (No Connect, Pin 4): Not internally connected, used for mechanical stability.
The LNK625PG integrates a high-voltage power MOSFET and control circuitry, eliminating the need for an optocoupler and secondary feedback control, simplifying the design of power supply circuits.
