FSL106MR from onsemi, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground: SENSEFET source terminal for the primary side and internal control ground. |
| 2 | VCC | power_in | Positive supply voltage input, fed from the transformer auxiliary winding after startup; the internal startup switch turns on when VCC reaches the 12 V UVLO upper threshold, and absolute maximum is 26 V. |
| 3 | VFB | input | Feedback voltage: non-inverting input of the PWM comparator, fed by an internal 0.4 mA current source and normally connected to an external capacitor and optocoupler, with a delay while CFB charges from 2.4 V to 6 V at 5 µA before protection triggers. |
| 4 | IPK | input | Peak current limit: adjusts the SENSEFET peak current limit, where the 0.4 mA feedback current is sent to this pin through an internal 6 kΩ resistor to GND in parallel with any external resistor to set the limit. |
| 5 | VSTR | input | Startup: connects to the rectified AC line voltage, and an internal switch charges the external VCC capacitor during startup then opens once VCC reaches 12 V (absolute maximum 650 V). |
| 6 | Drain | passive | SENSEFET drain, designed to connect directly to the transformer primary and capable of switching up to 650 V, with trace length to the transformer kept as short as possible to minimize leakage inductance. |
| 7 | Drain | passive | SENSEFET drain, designed to connect directly to the transformer primary and capable of switching up to 650 V, with trace length to the transformer kept as short as possible to minimize leakage inductance. |
| 8 | Drain | passive | SENSEFET drain, designed to connect directly to the transformer primary and capable of switching up to 650 V, with trace length to the transformer kept as short as possible to minimize leakage inductance. |
