The LZC8650C acts as the brain of offline AC/DC flyback and non-isolated Buck-Boost topologies. It transitions traditional, lossy hard-switching systems into smooth, resonant networks.
operates reliably from -40°C to 125°C . Package Thermal Resistance ( θJAtheta sub cap J cap A end-sub ): 100 °C/W for the SOIC-8 package architecture. 💎 Core Features and Advantages
The 'C' variant is marketed for higher performance , offering slightly better efficiency at high loads (above 1.2A), while the 'B' version is more cost-effective for general-purpose drivers. lzc8650c ic datasheet pdf better
Further simplification of the circuit design. Better Alternatives and Equivalents If you are looking to replace the
First, a quick primer. The LZC8650C is a . While its core architecture is designed for general DC-DC conversion, it has gained significant popularity in the LED driver market due to its high-voltage input range and constant-current capability. The LZC8650C acts as the brain of offline
Totem-pole gate driver output for the external power MOSFET. VDD IC Power supply pin. 7 OTP
These values define the safe operating area for the LZC8650C. Designing within these limits ensures product longevity. | | Symbol | Condition | Min | Typ | Max | Unit | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | Operating Current | I_op | ( C_DRV = 1.5nF ) | - | 1.5 | - | mA | | VDD Turn-on Threshold | VDD_ON | - | 18.1 | 19.8 | 21.5 | V | | Supply Voltage | VDD | Normal operation | 11 | - | 23 | V | | Junction Temperature | T_J | Operating range | -40 | - | 125 | °C | | VDD/DRV Pin Voltage | V_MAX | Absolute maximum rating | - | - | 30 | V | | ESD - HBM | V_ESD | Human Body Model | - | 2 | - | kV | Package Thermal Resistance ( θJAtheta sub cap J
