Hi Sir,​ALED6001 eDesign show BJT is as the red rectangle.However, most PNP BJT is show as below picture.I search some data, they show exchanging BJT's E and C, BJT can work. However, the hfe will decrease and the BJT cannot afford high voltage.Below...

ALED6001 Boost path

2021-04-26
Hi Sir,My project is Vin=9~16V,LED: 3 pcs in one stringVf=3.25I use eDesignSuite.The reference design is that it still use boost path, but the output voltage shows 10.1V.Is the boost no use in this condition? Dose it have any side effect? Low efficie...
