Chip Description
The EG1611 chip is a control chip specifically designed for push-pull boost inverters. It provides battery undervoltage and overvoltage shutdown, undervoltage buzzer, and overcurrent shutdown protection. It outputs two push-pull mode 40K-100KHz PWM signals. The voltage feedback uses a shallow closed-loop voltage regulation mode, which can achieve the highest voltage limit, preventing excessively high voltage during no-load operation that could burn MOS tubes. Simultaneously, it saves the output filter inductor of the transformer, reducing overall cost and PCB space.
