TNY286DG-TL from POWER INTEGRATIONS, in a SO-7. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN/UV | input | ENABLE/UNDERVOLTAGE input. Enable input controls MOSFET switching via a low-impedance source follower (~1.2 V, sink up to ~115 uA). Also senses line undervoltage via an external resistor to the DC line (threshold ~25 uA / ~75-115 uA). |
| 2 | BP/M | power_in | BYPASS/MULTI-FUNCTION pin. Connection for external bypass capacitor to the internally generated 5.85 V rail; capacitor value (0.1 / 1 / 10 uF) selects the current-limit mode (standard / reduced / increased). Also provides latch-off shutdown when current into the pin exceeds ISD, enabling output OVP with an external Zener. |
| 4 | D | power_in | DRAIN pin. High-voltage power MOSFET drain (725 V rated). Provides internal operating current for both start-up and steady-state through an internal high-voltage current source. Connects to the transformer primary in flyback topology. |
| 5 | S | power_in | SOURCE pin. Internally connected to the power MOSFET source for high-voltage power return and control-circuit common. Pins 5-8 are all tied to SOURCE and typically joined on the PCB to provide heat sinking. |
| 6 | S | power_in | SOURCE pin. Internally connected to MOSFET source; tie to pins 5/7/8 for power return and PCB heat sinking. |
| 7 | S | power_in | SOURCE pin. Internally connected to MOSFET source; tie to pins 5/6/8 for power return and PCB heat sinking. |
| 8 | S | power_in | SOURCE pin. Internally connected to MOSFET source; tie to pins 5/6/7 for power return and PCB heat sinking. |
