Overview
GP8891XS is a self-powered constant voltage/constant current primary-side feedback control IC, suitable for chargers and adapters. Proprietary output line loss compensation technology effectively compensates for the voltage drop caused by output current losses in the output cable. Built-in startup circuit eliminates external startup resistors; integrated FB pull-down resistor and CS sampling resistor simplify the peripheral design. Built-in loop compensation circuit eliminates external compensation components, ensuring excellent system stability. Achieves superior CV/CC characteristics, meeting standby power consumption below 75mW. Multiple protection features including open-circuit protection, OVP, output short-circuit protection, and secondary Schottky short-circuit protection. Unique single-cycle peak current shutdown mechanism prevents various failures caused by transistor overcurrent. SOP7 package.
