【产品】必易推出集成整流桥、续流二极管的KP1077XWP系列,使用全新ASOP-7封装
LED通用照明经过十多年的发展,市场竞争已愈演愈烈,在LED驱动电源发展过程中,缩减外围、降低系统成本、提升可靠性一直是工程师朋友孜孜不倦的追求,时至今日,驱动技术已日趋成熟,大家也在思考是否有一种方案能够成为最终版?必易微电子在系统集成方面一直走在行业前列,2019年在业内率先推出 KP1054X/KP1075X (集成续流二极管) 系列,一时间好评如潮,受到很多客户的青睐。今年,必易再次推出全新一代解决方案---集成整流桥、续流二极管的KP1077XWP系列,使用全新ASOP-7封装。
方案优势
方案优势:
1.集成续流二极管和整流桥
2.极小 Toff_min (1uS)、支持工作频率高达 300Khz,完美适用于 DOB 应用
3.支持 OTP 分段可调,使灯珠在不同结构件,不同散热条件下都能得到充分的保护
4.优异的线电压调整率和恒流精度
5.完备的系统保护,保证产线高良率
LPF方案迭代过程
近两年来,通用照明IC迭代频繁,必易的LPF产品也不断推陈出新,从最初的省VCC电容方案 (1052X),到集成续流二极管方案 (1054X),再进化至集成整流桥、续流二极管方案 (1077X),外围元器件不断减少,系统越来越简单。
省 VDD 电容
省 VDD 电容、续流二极管
省 VDD 电容、续流二极管、整流桥
DEMO介绍
电气参数:输入 176~264V,输入功率 20W,输出 150V/120mA
1)BOM:
仅需5 个元器件!更小的体积,更简单的备货,更高性价比的 BOM!
2)基本电气参数:150V/120mA 规格,KP10771WP 的效率为 92.6% 左右 @220Vac,调整率 <2%
3)IC 温升对比参数:
集成的器件越来越多,工程师朋友一定会关心温升情况,实测在 DOB 应用下,150V 120mA 规格中,温升约 85℃ (28.5℃ 环温下,壳温约 113℃),和上一代集成二极管产品 KP10751VP 基本一致;
4)OTP 分档功能:
IC 的 OTP 点可以通过一颗普通 0805 电阻来调节,从而满足不同的结构件散热能力,以及不同客户对温度的要求,保证产品可靠性,提高整灯使用寿命。在大部分应用中,该电阻可以不放,此时 IC 的 OTP 点为 125℃,较适合 DOB 的应用环境。
5)多种规格任意选择:
总结
KP1077XWP,集成整流桥和续流二极管,全新一代 LPF 解决方案,极简的系统外围,前所未有的性价比,优良的可靠性,真正 DOB 方案的不“二”之选,欢迎工程师朋友索样。
