The document introduces the features and characteristics of L6562, including BCD technology, transition mode control, proprietary multiplier design, adjustable output overvoltage protection, ultra-low startup current, and low quiescent current.
The L6562 is a current‑mode PFC controller operating in Transition Mode (TM). It features a proprietary multiplier design for low THD, an internal 1 % reference, ultra‑low start‑up current (<70 µA) and quiescent current (<4 mA), as well as an on‑chip filter on the current‑sense input and a disable function for remote ON/OFF.
Designed for IEC‑61000‑3‑2 compliant SMPS up to 300 W, the device drives MOSFET or IGBT gate drivers with a 600 mA source and 800 mA sink capability, supports a wide supply voltage range (10.3 V‑22 V), and includes a two‑step over‑voltage protection scheme.
| Start‑up current | <70 µA |
|---|---|
| Quiescent current | <4 mA |
| Output driver current capability | 600 mA source / 800 mA sink |
| Internal reference accuracy | 1 % @ 25 °C |
| Static over‑voltage protection threshold | 2.25 V – 2.4 V |
| Package types | DIP‑8, SO‑8 (ECOPACK®) |
The start‑up current is less than 70 µA before the device turns on.
The quiescent current after start‑up is less than 4 mA.
It can source up to 600 mA and sink up to 800 mA.
