用于 LED 照明的谐振开关驱动器控制器

TPS92023 是一款高性能谐振-开关 LED 驱动器控制器。 它设计用于较高功率 LED 照明系统。 相对于传统的半桥转换器，TPS92023 使用拓扑结构为 LLC 的谐振开关，来实现极高的效率。可编程死区时间用最少的磁化电流来实现零电压开关，从而在多种应用中大大提高了系统效率。TPS92023 能够以两个开关频率模式运行。 当负载电流为恒定时，固定频率可实现简单设计，而可变开关可针对电流不断变化的负载实现最佳的闭环控制。 内部振荡器支持 30kHz 至 380kHz 范围内的开关频率。 这个高精度振荡器实现了限制在 4% 耐受以内的最小开关频率，从而使得设计人员能够避免功率级的 • 用于多灯串 LED 照明应用的线路电平控制 (LLC) 谐振开关驱动器控制器 \n• 固定或变化的开关频率控制 \n• 可编程死区时间以实现最佳效率 \n• 过流保护 \n• 偏置电压欠压闭锁 (UVLO) 和过压保护 (OVP) \n• 运行温度范围：-40°C 至 125°C \n• 小外形尺寸集成电路 (SOIC) 8 引脚封装;
