Hello,
I am working on a PWM dimmable offline constant current LED driver with 230Vac input and output of 150V, 100mA. The MP4054A and MP4027 seem to fit right and both have the same sample circuit “A19 Bulb Driver”, which I want to follow. In fact their datasheets also seem to be identical, apart from the formatting. So which one should I chosse? The only difference seems to be in the pricing and availability from distributors.
