【产品】调光型、降压型高功率因数LED恒流功率开关KP14664M-PWM，15mW超低待机功耗，封装类型 SOP-7
必易微推出的KP14664M 是高度集成的恒流 LED 功率开关，芯片采用了准谐振的工作模式，同时加以有源功率因数校正控制技术可以满足高功率因数、低谐波失真和高效率的性能。KP14664M 内部集成有高压 600V 功率 MOSFET 和高压供电电路，简化了系统的设计和生产成本。芯片通过独有的恒流控制算法，可以获得高精度的恒流输出，且输出的线电压和负载调整率表现优异。
【应用】国产隔离型恒流LED功率开关KP13254用于照明灯具，输出功率达35W，设计简单效率高
客户做一款小功率的照明灯具，想找个内置MOS的LED驱动方案，芯片需要带隔离，恒流输出，要求功率大于30W。本文推荐必易微电子的KP13254高度集成的隔离型恒流LED功率开关，采用了原边反馈准谐振的工作模式，同时加以有源功率因数校正控制技术。
【产品】原边控制、恒流模式LED功率开关KP1191等，±5%恒流精度
必易微电子（KIWI）推出的KP1191、KP1192、KP1193、KP1194是高度集成的原边控制、恒流模式LED功率开关，芯片工作在电感电流断续模式，适用于隔离反激型LED恒流电源。
