LGS6304X - 60V boost, buck and buck-boost LED constant current driver

2025-04-08
LGS6304X是一款集成了功率开关的多操作模式驱动芯片,适用于宽输入/输出DC-DC LED,具有3V至60V的宽输入电压范围。该芯片内置350mΩ功率开关,可提供至少1.5A峰值输入电流容量,其输出电流可通过外部采样电阻进行调整。LGS6304X采用电流模式控制,具有优异的响应速度和易于环路补偿。它还具有SKIP控制模式,结合低静态电流和高开关频率,在宽范围的负载电流下实现高效率。其他功能包括软启动、热关断、输入欠压保护、输出过压保护和周期性电流限制保护。LGS6304X可选择不同的电阻采样电阻RSence,以实现高精度数字和模拟输出电流调节,包括两个特定型号LGS63040和LGS63042。
