Один из самых простых способов использовать LM2587-ADJ или LM2577-ADJ
Варианты включения в даташит.У меня вариант с 2587 работает на самодельной зарядке для 3-х баночных липолек,с зарядным током до 1,8 ампера.Пока нареканий не было.

Речь шла о мощном преобразователе, а не о 25-и ватном…
LM2577 до 3-х Ампер выдает, мало разве? 20в*3а=60Вт, можно к ней ключ присобачить и хоть 20А снимать или на TL494 сделать хоть скока хочешь. natahaus.ru/…/silovaja_jelektronika_ot_prostogo_k_… очень советую к прочтению.
