OB2365AMP from OB On Bright Elec, in a SOT-23-6. 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 | GND | power_in | Device ground reference. All internal analog and control circuits are referenced to this pin. |
| 2 | FB | input | Feedback input from the secondary-side optocoupler. The internal current loop compares CS against FB to regulate the peak primary current. Absolute max -0.3 to 7 V. |
| 3 | DEM | input | Demagnetization / auxiliary-winding sense input used for QR valley detection, external NTC-based OTP, and output OVP sensing (OVP trip level set by the resistor between the aux winding and this pin). Absolute max -0.3 to 7 V. |
| 4 | CS | input | Current-sense input from the primary MOSFET source resistor. Provides cycle-by-cycle peak current limiting and inner-loop control. Absolute max -0.3 to 7 V; negative spikes down to -1 V permitted under limited duty/current. |
| 5 | VCC | power_in | Chip supply voltage, typically from the auxiliary winding after startup. Recommended operating range 12 to 26 V; absolute max 29.5 V. Includes UVLO with hysteresis and VCC OVP protection. |
| 6 | GATE | output | Gate driver output for the external primary-side power MOSFET. Totem-pole driver providing the PWM switching waveform. |
