电源管理

PL3380L是一系列AC/DC非隔离降压型恒压输出芯片，适用于90Vac~265Vac全电压输入的非隔离电源。\n\n其内部集成了高压功率开关，采用专利电压电流控制技术，无需外部电压反馈和电流侦测电路即可实现精确的电压和电流调节，极大的方便客户使用。\n\nPL3380L的复合模式的应用使芯片能够实现低静态功耗、低音频噪音、高效率。轻载时芯片工作在PFM模式，随着负载增加，芯片会逐渐进入PWM模式，可保证系统低功耗待机，高效率工作。\n\nPL3380L 同时具有多种保护功能：VCC 欠压保护、VCC 过压保护、逐周期峰值电流检测、输出开路保护、输出短路保护和过温保护等。\n\nPL3380 • 1T增强型ET8051内核\n• 集成最多16+4(移位)个电容触摸按键\n• 内置4K字节Flash与128字节EEPROM\n• 工作温度:-40°C~125C\n• 集成8通道11位ADC\n• 最多22个双向通用I/O口\n• 封装形式:24/20/16/8管脚\n• Flash程序区:40年、10万次\n• EEPROM数据区:40年、50万次;
