By utilizing a built-in high-precision multiplier and a unique current control algorithm, the IC forces the input current to follow the waveform of the input voltage. This ensures compliance with strict international lighting regulations regarding power grid harmonics. 3. Comprehensive Built-in Protection
Current sense input. It monitors the primary peak current through a sensing resistor connected to the MOSFET source.
Disclaimer: This write-up is a generalized technical summary based on the typical behavior of ICs in the LZC86xx series and standard LED driver topologies. For precise circuit design, warranty validation, and safety compliance, the official specific manufacturer datasheet must be consulted.
Error amplifier inverting input. Connects to the feedback loop to regulate output current. COMP
) : Calculate the primary-side peak current value using the maximum power capacity of the core. Ensure the sense resistor is non-inductive to prevent unwanted signal deviations on Pin 3.
The (also marketed under the brand DIOO as ) is a high-performance, single-stage LED driver IC designed for offline flyback power converters. It is widely used in LED lighting for its ability to provide high power factor (PF > 0.95) and low total harmonic distortion (THD < 10%). 🛠️ Key Technical Specifications
Unlike harsh latching thermal shutdown structures, the LZC8650C tracks ambient temperatures using its . When local heat passes safe limits, the controller decreases the target output driving current linearly (
Integrated Over-Temperature Protection (OTP) with hysteresis, VDD over-voltage protection (OVP), cycle-by-cycle current limiting on the CS pin, and output short-to-GND protection. Fast Startup: Minimized startup current.
Thermal protection and foldback threshold adjustments. Programs the precise temperature fallback point using an external NTC resistor network.
