    I got one some time ago, i used it today. CONST: 1) Mine isn't a LM2577 but a XL6009E1. 2) The input voltage is 5v to 32v (page 5 of datasheet v 1.1) and not 3v to 30v. 3) The output voltage can go up to 60v and not to 35v, the output cap is 100uf 50v so it can explode. 4) The capacitor on the input (220uf 35v) is rotated and soldered by only the negative pin, the other on the positive isn't soldered. I'm not good with smd soldering so probably i'm gonna destroy it in the tentative of fix it... PRO: 1) Low price.

    Отличный преобразователь, греется в меру, лучше поставить радиатор на микросхему, работать начинает с 3 вольт, отличное решение для резервного зарядного, не убьет аккумулятор, т.к. перестанет работать разрядив его до 3 вольт, использую для поднятия напряжения до 12 вольт, отличное качество пайки, все прекрасно работает, спасибо Банггуд)))
