Detects when the inductor current reaches zero for QRM operation and provides line regulation. VIN/VDD: Power supply pin for the IC.
The “C” often indicates a specific die version or temperature range (e.g., commercial 0°C to 85°C vs. industrial -40°C to 85°C).
The datasheet highlights a low quiescent current (operating current when the IC is active but the load is low). Low quiescent current is vital for meeting global energy standards such as Energy Star or the EU Ecodesign Directive, ensuring minimal power waste when the light is active but dimmed or in standby.
A: In many cases, the pinout and functionality are similar. However, the feedback voltage (Vref) may differ (e.g., 0.1V vs. 0.2V), which changes Rsense values. Always consult the LZC8650C IC datasheet PDF for exact values. lzc8650c ic datasheet pdf
