SN6505ADBVR from Texas Instruments, 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 | D1 | output | Open-drain output of the first power MOSFET. Typically connected to one outer terminal of the center-tap transformer. Peak switch current up to 2.4 A; on-resistance 0.16 Ω typ at VCC = 4.5 V. Keep external trace short due to large currents. |
| 2 | VCC | power_in | Device supply pin, 2.25 V to 5.5 V. Bypass with a 4.7 µF or greater low-ESR capacitor. When VCC ≤ 2.25 V an internal UVLO trips and turns both outputs off. |
| 3 | D2 | output | Open-drain output of the second power MOSFET. Typically connected to the opposite outer terminal of the center-tap transformer. Peak switch current up to 2.4 A; on-resistance 0.16 Ω typ at VCC = 4.5 V. |
| 4 | GND | power_in | Ground return, connected to the source of the power MOSFETs via an internal sense circuit. Must be connected to a low-inductance quality ground plane due to large primary currents. |
| 5 | EN | input | Enable input. Turns the device on when high; grounding or leaving floating disables all internal circuitry. If unused, tie directly to VCC. Logic thresholds referenced to VCC (VIH ≤ 0.7·VCC, VIL ≥ 0.3·VCC). |
| 6 | CLK | input | External clock input for the switching frequency (100 kHz-600 kHz on SN6505A, 100 kHz-1600 kHz on SN6505B). Internally pulled to GND; if no valid clock is detected within tCLKTIMER (10-25 µs) the device switches automatically to its internal oscillator. |
