Lzc8650c Ic Datasheet Pdf _verified_

: Features an integrated Over-Temperature Protection (OTP) that can fold back the output current based on temperature settings to prevent overheating.

Protects the external MOSFET from over-current destruction.

Typically achieves a power factor >0.95 and low Total Harmonic Distortion (THD < 10%) at standard AC voltages. Quasi-Resonant Mode (QRM): lzc8650c ic datasheet pdf

): 1.5 mA (Typical with a 1.5 nF gate load) — High efficiency during continuous high-frequency switching. 253.0 mV ±plus or minus

Unlike hard thermal-shutdown controllers that completely cut off light outputs when hot, the LZC8650C utilizes a progressive, . Designers attach an NTC thermistor to the OTP/TS pin. When local enclosures heat up: The IC monitors the dropping resistance on the OTP pin. : Shuts down the gate driver if the

: Shuts down the gate driver if the supply voltage exceeds safe functional thresholds.

The ZCD circuit monitors the core demagnetization of the flyback transformer through an auxiliary winding. When the secondary-side current drops to zero, the voltage on the ZCD pin falls below an internal threshold, instructing the GATE driver to turn the external MOSFET back on. This ensures seamless Boundary Conduction Mode operation. 5. Built-In Protection Features the LZC8650C utilizes a progressive

Integrates active PFC to meet stringent power quality standards.

: Controls output current accurately using information from the primary side, removing the need for an opto-coupler or secondary feedback components.
