STMicroelectronics · AC-DC Controllers And Regulators · SO-8
L6562D from STMicroelectronics, in a SO-8. 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 | Inverting input of the error amplifier, receiving the PFC output voltage through a resistor divider, with the feedback threshold at 2.5 V (2.465 V to 2.535 V at Tj = 25 °C). |
| 2 | COMP | output | Error amplifier output, with a compensation network connected between this pin and INV (pin 1) to ensure voltage-loop stability, high power factor and low THD. |
| 3 | MULT | input | Main multiplier input, connected to the rectified mains voltage through a resistor divider to provide the sinusoidal current-loop reference, with a linear operating range of 0 to 3 V. |
| 4 | CS | input | Input to the PWM comparator that senses MOSFET current through a resistor and compares it with the multiplier's sinusoidal reference to determine MOSFET turn-off, with a delay to output of 200 to 350 ns. |
| 5 | ZCD | input | Boost inductor demagnetization sensing input for transition-mode operation, where a negative-going edge triggers MOSFET turn-on (triggering voltage 1.6 V, arming voltage 2.1 V on the positive-going edge). |
| 6 | GND | power_in | Ground, serving as the current return for both the signal part of the IC and the gate driver. |
| 7 | GD | output | Totem-pole gate driver output for power MOSFETs and IGBTs, rated 600 mA source and 800 mA sink peak current, with the high-level voltage clamped at about 12 V. |
| 8 | Vcc | power_in | Supply voltage for both the signal part of the IC and the gate driver, with an upper limit extended to 22 V minimum; turn-on threshold is 11 to 13 V and turn-off threshold is 8.7 to 10.3 V. |
