DPA425PN from POWER INTEGRATIONS, 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 | EXTERNAL CURRENT LIMIT (X) | input | Input pin for external current limit adjustment, which can be programmed between 25% and 100% of the default current limit, and for remote ON/OFF; connecting it to SOURCE disables both functions. |
| 2 | SOURCE (S) | power_in | Output MOSFET source connection for the power return and the primary side control circuit common and reference point. |
| 3 | LINE-SENSE (L) | input | Input pin for line overvoltage and undervoltage lockout, line feed-forward with DCMAX reduction, remote ON/OFF and synchronization; connecting it to SOURCE disables all these functions. |
| 4 | FREQUENCY (F) | input | Input pin selecting the switching frequency, 400 kHz when connected to SOURCE and 300 kHz when connected to CONTROL, and it should not be left open. |
| 5 | SOURCE (S) | power_in | Output MOSFET source connection for the power return and the primary side control circuit common and reference point. |
| 6 | SOURCE (S) | power_in | Output MOSFET source connection for the power return and the primary side control circuit common and reference point. |
| 7 | DRAIN (D) | power_out | High-voltage power MOSFET drain output rated for 220 V BVDSS, which draws the internal startup bias current through a switched high-voltage current source and senses drain current limit. |
| 8 | CONTROL (C) | power_in | Error amplifier and feedback current input and supply pin that is regulated near 5.8 V and needs a bypass capacitor connected closely between CONTROL and SOURCE. |
