M8915可替代BP2325A下面将是M8915的规格书

概述：M8915是一款带有源功率因数校正的高精度非隔离降压型LED恒流控制芯片，M8915集成有源功率因数校正电路，可以实现很高的功率因数和很低的总谐波失真。

由于工作在电感电流临界连续模式，功率MOS管处于零电流开通状态，开关损耗得以减小，同时电感的利用率也较高。

M8915内部集成500V功率MOSFET,只需要很少的外围器件，即可实现优异的恒流特性。

M8915采用专利的浮地构架，对电感电流进行全周期采样，可实现高精度输出恒流控制，并达到优异的线电压调整率和负载调整率。

另外，M8915具有过热调节功能，在驱动电源过热时减小输出电流，以提高系统的可靠性。

特点：应用：■内置有源功率因数校正■GU10/E27 LED球泡灯、射灯■电感电流临界连续模式■LED PAR灯■高性能的线电压调整率和负载调整率■LED日光灯■±3%输出电流精度■其它■内置500V功率MOSFET■启动电流■高达95%的系统效率■多重保护功能LED开路/短路保护电流采样电阻开路保护逐周期原边电流限流芯片供电过压/欠压保护自动重启功能过热调节功能■采用SOP-8封装典型应用：图1 M8915典型应用图管脚排列图:图2 M8915管脚排列图管脚描述：极限参数：电气参数：Tc=25℃注5：规格书的最小、最大规范范围由测试保证，典型值由设计、测试或统计分析保证。

芯片内部结构框图：图3 M8915内部框图应用信息M8915是一款非隔离式、有源功率因数校正LED恒流控制芯片，工作在电感电流临界连续模式，芯片可以实现很高的功率因数和高效率。

启动系统上电后，经过整流后的电压通过启动电阻给VDD引脚的电容充电，当VDD电压上升到启动阈值电压后，芯片内部控制电路开始工作，COMP电压被上拉到1.7V，M8915开始输出脉冲信号，COMP电压从1.7V开始逐渐上升，原边峰值电流随之上升，从而实现输出LED电流的软启动，有效防止输出电流过冲。
