The LZC8650C uses a standard 8-pin Small Outline Package (SOP8/SOIC-8) format. Below is the functional mapping derived from the LZC8650 Pin Description: Pin Number Functional Description CMP Whether you are a student debugging a lab
Uses a proprietary real-current control method for accurate LED current regulation. Protection Suite: Built-in over-temperature protection with hysteresis. Input and VDD over/under voltage protection. Short Circuit: Reliable output short-to-GND protection. Cycle-by-cycle current limiting on the CS pin. Pinout Configuration (SOP8 Package) The LZC8650C typically utilizes an SOP8 (SOIC-8) package with the following pin functions: Description
The LZC8650C was designed to be the "Silent Guardian."
The LZC8650C is a compact controller in an package, designed to handle up to 100W of power. Its 8 pins are configured as follows:
Detects output shorts to ground (GND).
The values of capacitors and resistors connected to the COMP pin determine the stability and response time of the system.
The LZC8650C operates in QRM, turning on the MOSFET when the drain voltage is at its lowest (valley switching). This minimizes switching noise and improves efficiency. It regulates the output current by calculating the secondary output current using the primary peak current and conduction time information. 3. Key Design Considerations
