SG3525ADTR from XBLW, in a SOP-16. 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 | Inv. Input | input | Inverting input of the error amplifier, whose common-mode range includes the reference voltage. |
| 2 | Noninv. Input | input | Noninverting input of the error amplifier, whose common-mode range includes the reference voltage. |
| 3 | Sync | input | Oscillator sync input, allowing multiple units to be slaved or a single unit to be synchronized to an external system clock. |
| 4 | OSC. Output | output | Oscillator output. |
| 5 | CT | passive | Oscillator timing capacitor connection; recommended 0.001 to 0.2 uF. |
| 6 | RT | passive | Oscillator timing resistor connection; recommended 2.0 to 150 kOhm. |
| 7 | Discharge | passive | Oscillator discharge pin; a single deadtime resistor (0 to 500 Ohm recommended) is connected between CT and Discharge. |
| 8 | Soft-Start | passive | Soft-start pin requiring only an external timing capacitor. |
| 9 | Compensation | bidirectional | Error amplifier output / compensation node feeding the PWM comparator. |
| 10 | Shutdown | input | Shutdown input controlling both the soft-start circuitry and the output stages, giving instantaneous turn-off through the PWM latch. |
| 11 | Output A | output | Totem-pole output A capable of sinking and sourcing in excess of 150 mA, with NOR logic giving a low output in the off-state. |
| 12 | Ground | power_in | Ground connection. |
| 13 | VC | power_in | Collector supply voltage for the output stage; recommended 4.5 to 35 V, 40 V maximum. |
| 14 | Output B | output | Totem-pole output B capable of sinking and sourcing in excess of 150 mA, with NOR logic giving a low output in the off-state. |
| 15 | VCC | power_in | Supply voltage input; recommended 8.0 to 35 V, 40 V maximum. |
| 16 | Vref | power_out | On-chip +5.1 V reference trimmed to ±1%; reference load current 0 to 20 mA recommended. |
