typical decay rate), keeping the luminaire illuminated safely at a dimmer setting rather than turning off completely. Typical LZC8650C Application Schematic Guide
Detected when the FB pin voltage drops below 0.7V for a prolonged duration. The IC stops switching and attempts an auto-restart sequence. The LED driving current is throttled backwards at
is optimized for PCB layout simplicity. Below are the typical pin functions: Ground reference for the IC.
As specific temperature inflection barriers are crossed (e.g., 123°C or 145°C depending on setting configuration), the internal reference drops smoothly.
: As the primary MOSFET switches, the auxiliary winding of the flyback transformer mirrors the secondary output voltage state.
According to the LZC8650 datasheet , here are the critical electrical parameters: Typically operates between 9.5V and 27V. Startup Current: Ultra-low, typically around Totem-pole gate driver output
Disclaimer: Always refer to the specific datasheet provided by the manufacturer of the IC you are using, as specifications can vary slightly between manufacturers.
Integrated four-stage temperature foldback function to protect the IC by reducing current as temperature rises. Voltage Protection: cap V sub cap D cap D end-sub
Real-current control for accurate output from the primary side Commonly available in SOT23-6 or SOIC-8 packages Protection Features
: Monitors the CS (Current Sense) pin to prevent inductor saturation.
Output of the internal Operational Transconductance Amplifier (OTA). An external resistor-capacitor (RC) network connects from this pin to ground to stabilize the primary constant current control loops.
