Lzc8650c Ic Datasheet Pdf Better [extra Quality] <2026 Update>

Features an integrated temperature foldback (OTP) function that automatically reduces output current as the temperature rises, preventing catastrophic failure. Typical Value / Range Supply Voltage (VDD) 9.5V to 27V (Operating range) Startup Current ~10 µA (Extremely low for quick start) Gate Drive Clamp 16V (Internal protection for external MOSFET) Operating Temperature -40°C to 125°C Pin Configuration and Functions The LZC8650C is commonly available in a SOP-8 package.

Integrated protections like Output Short-Circuit Protection and VDD Over-Voltage Protection ensure reliability in harsh environments. lzc8650c ic datasheet pdf better

Current sense pin. It monitors the voltage across a sense resistor connected to the primary MOSFET's source for cycle-by-cycle current limiting. GND (Pin 4): Power and signal ground. Current sense pin

Gate driver output to control the external power MOSFET. VDD (Pin 6): Power supply pin for the IC. Gate driver output to control the external power MOSFET

Feedback pin for zero-crossing detection (ZCD) and over-voltage protection (OVP). It senses reflected voltage from the auxiliary winding.
