AL6562AS-13 from Diodes Incorporated, in a SO-8. 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 | INV | input | Inverting input of the internal error amplifier. Connects via a resistor divider from the regulated output voltage; internal reference is 2.5V (1% @ TJ=+25°C). Also doubles as ENABLE/DISABLE: below ~0.3V shuts the IC down; restart threshold ~0.48V. |
| 2 | COMP | output | Error amplifier output. External R-C compensation network between INV (pin 1) and COMP sets loop bandwidth for high PF and low THD. Upper clamp ~5.8V, lower clamp ~2.25V. |
| 3 | MULT | input | Input to the internal multiplier. Connect to the rectified mains via an external resistor divider to provide the sinusoidal current-reference for the control loop. Linear operating range 0-3V (up to 3.5V). |
| 4 | CS | input | Current sense input. MOSFET current is sensed across an external resistor and compared against the internal sinusoidal reference to terminate the MOSFET on-time. Includes ~200 ns internal Leading-Edge Blanking; internal clamp ~1.7V. |
| 5 | ZCD | input | Zero Current Detection input from the boost inductor's auxiliary winding (or R-C from MOSFET drain). A negative-going edge (arming 2.1V / trigger 1.6V) turns the MOSFET on for Transition-Mode operation. Internally clamped (upper ~5.2V, lower ~0.65V); max source -50 mA / sink 10 mA. |
| 6 | GND | power_in | System ground. Common return for both signal circuitry and the gate-drive stage. |
| 7 | GD | output | Gate-driver output. Totem-pole push-pull stage driving an external MOSFET with 600 mA source / 800 mA sink peak capability. Output high level internally clamped to ~12V to protect the external MOSFET gate when VCC exceeds this level. |
| 8 | VCC | power_in | Supply pin for the signal section and the gate driver. Operating range ~10.3-22V after turn-on (VCC_ON ≈ 12V, VCC_OFF ≈ 9.5V). Internal 24V Zener protects the IC from transient overvoltage. |
