Product Model: LP8776AL
LP8776AL is an isolated constant voltage PWM controller suitable for secondary-side controlled flyback applications. The LP8776AL uses a unique high and low voltage output current compensation method, so that the output overcurrent (IOCP) does not change with the input voltage. The chip uses a multi-mode constant voltage control method: peak current control mode; the external RT resistor sets the operating frequency, which starts to decrease at frequencies below medium load to improve average efficiency, and in light load or no-load conditions, the system operates in burst mode. The chip uses a unique frequency jitter technology to improve EMI performance. The LP8776AL has multiple protection functions, including VCC undervoltage protection, VCC overvoltage protection, output overload protection, output synchronous rectification short-circuit protection, output short-circuit protection, overtemperature protection, output overvoltage protection, and CS resistor short-circuit protection. The LP8776AL is packaged in a SOT23-6L package.
