Jakie przetwornice step-down 12-16V do 5V/1A w SMD polecacie z PL?

Co polecicie jako step-down z 12-16V do 5V/1A? Oby bylo do kupienia w PL
i nieszczegolnie drogie. I najlepiej w obudowie SMD. Wynalazki Maxima znam.

Poraża tylko cena: około 80 zł + VAT.
To już wolę MC34063 za 3 zł plus dławik w podobnej cenie.

Wyłamię się: do obniżania napięcia ostatnio "męczę" stabilizator
LM2940-12 (ale -5 też są , głównie dla tego, że mam za mało miejsca
na jakąś przetwornicę+dławik+diodę (rasowanie "gotowca"), a potrzebowałem
coś, co z Uin=12,5-24V zrobi mi 12V/0,5A, a wyłączy się przy Uin>30V...

P.S. W TME LM2940CS-5 kosztuje 3(1szt) zł, 2(25szt)...
