Vout 10 15 20 Vout(V) 20 mA 30 mA 25 30 图 2. SM2311E 应用电路原理图 效率设计理论 图 4 所示的应用电路工作效率计算如下： η PLED n VLED ILED n VLED PIN VIN ILED VIN 其中 Vin 是系统输入电源电压，VLED 是单个 LED 工作电压降，ILED 是 LED 导通电流。可看出系统串联的 LED 数量 n 越大，系统工作效率越高。 系统设计过程中，需根据应用环境调整 SM2311E 的 OUT 端口工作电压，优化 η 值。 LED 串联数量设计 系统串接的 LED 数量设计需考虑以下两个方面： 1) 图 4 电路中，OUT 端口电压 VOUT = Vin n VLED ，为保证芯片正常工作，需保证 OUT 端口电压 VOUT > VOUT_MIN； 2) 芯片 OUT 端口电压越低，系统工作效率越高。...
