【产品】新款低谐波、高精度、高功率因数ACDC隔离恒压控制器KP1513SPA，轻松实现50mW待机

时间： 2021-04-20 来源：必易微电子

技术问答

随着智能照明的快速发展，用户越来越重视智能灯具的使用体验以及节能环保，高PF、低谐波、低待机、快速启动等性能指标，这些新要求已然成为了用户的“刚需”。同时随着新欧标针对谐波的法规 IEC61000-3-2：2018 的推出，原来无谐波要求的隔离型灯具、灯带适配器等产品无法再满足新法规的要求，且灯具的标准与适配器的标准有走向统一的趋势。基于此，必易微电子推出高PF、低谐波、低待机、超快启动、动态响应优异的单级PFC AC-DC隔离恒压控制器KP1513SPA。

原理介绍

KP1513SPA 采用准谐振工作方式，系统工作效率高。内置 THD补偿线路，满足高PF的同时也满足低THD要求。轻载降频模式可以提高系统在负载较轻时的效率。芯片可以设定最低工作频率，能保证系统在超轻假负载条件下正常工作，满足超低待机损耗要求。

电源性能

KP1513SPA 采用原边控制方式，不需要光耦。其内置的输出电压采样方式可以保证输出电压精度在±3%以内，并且在轻载条件下保持较好的输出电压精度。KP1513SPA 内置自适应的输出电压限制机制，保证负载动态条件下输出电压的波动在5%以内。

产品优势

1、轻松实现50mW超低待机

2、全电压功率因数 >0.95 ，THD<5%

3、谐波满足新欧标 IEC61000-3-2:2018

4、高压供电，快速启动，启动时间 <0.5S

5、集成完备的保护功能

6、极低的线性和负载调整率 (±2%)

7、媲美 SSR 的动态响应能力

8、快速动态 ±10/20% 两档可选，满足不同应用场景

9、轻载满足分次谐波 class C 标准

性能参数

输入：90~264Vac/47~63Hz

输出：24V/1A

性能表现：

1、待机功耗<50mW@264Vac/50Hz，空载

2、线性调整率 ±0.5%

3、负载调整率 ±1%

4、总谐波<5%@90~264Vac

5、启动时间<0.2S@90Vac 满载

电源性能

待机功耗<50mW

目前市面上同类产品待机功耗最好的做到 200mW 以内，而 KP1513SP 可以轻松实现 50mW 以内待机。

线性/负载调整率 ±2%以内

全电压和全负载范围内输出电压精度高，±2% 以内，量产一致性好。

平均效率满足六级能效

采用 KP1513SPA 的独立式电源或灯具驱动可以同时满足灯具和适配器的能效标准，可以使得产品设计标准化。

快速启动，启动时间<0.2S

任意负载和输入电压条件下，可以满足照明驱动启动时间 500ms 以内要求。

THD<5%

全电压范围下，THD<5%，可以满足不同客户的谐波需求。

分次谐波满足IEC61000-3-2 Class C

传导

传导余量充足，>6dB，EMC 性能优异

CDN

CDN 余量充足，>6dB，EMC 性能优异。
