At its core, the LZC8650C minimizes manufacturing bills-of-materials (BOM) by eliminating secondary-side optocouplers and feedback loops entirely. It dynamically regulates constant output current by relying strictly on the auxiliary winding reflection voltage.

The is a high-performance, single-stage LED driver integrated circuit (IC) primarily used in offline AC/DC flyback power converters. It is designed by Lozen Semiconductor (菱奇半导体) and is widely used in high-power LED applications like street lighting and industrial lamps. Core Specifications & Features Proprietary method for high-accuracy LED current regulation

The LZC8650C integrates several critical functions for efficient LED driving:

You should always consult the specific datasheet PDF from the manufacturer to check the precise maximum supply voltage (often 33V33 cap V for VDD) and thermal ratings (e.g., 150∘C150 raised to the composed with power cap C junction temperature). 6.

The LZC8650C shines because of its use of (PSR). This means the chip regulates the output current by sensing the primary-side information without needing a feedback loop from the secondary side. This dramatically reduces component count, cost, and PCB size. Furthermore, it operates in Quasi-Resonant Mode (QRM) which maximizes efficiency by reducing the MOSFET's switching losses and minimizing EMI, while its valley detection circuit ensures consistent current accuracy even as the line voltage fluctuates.
