Real-current control for accurate output from the primary side Commonly available in SOT23-6 or SOIC-8 packages Protection Features lzc8650c ic datasheet pdf

Monitors the CS pin voltage continuously. If the voltage exceeds the 1.1V threshold, the gate drive instantly shuts off for that switching cycle.

Pin used to adjust the thermal foldback trigger point using an external Negative Temperature Coefficient (NTC) resistor network. : Quasi-Resonance (QR) mode, which reduces MOSFET switching

The auxiliary winding outputs a reflected voltage to a resistor divider connected to the FB pin . The IC samples this voltage when the secondary inductor current reaches zero. This value is processed against the 253mV internal reference ( VREFcap V sub cap R cap E cap F end-sub ) to modulate the PWM on-time.

Reliability is a major factor in commercial LED driver design. The LZC8650C integrates multiple layers of protection to safely handle unexpected circuit faults:

Dual electrolytic networks rated for high temperature (typically
