    Part Number: LM2594 What is the difference between LM2594M-5.0-NOPB and LM2594 HV M-5.0/NOPB, is it only the supply voltage? Is it different die or just a testing process of the same die sorting out devices to LM2594M-5.0-NOPB and LM2594 HV M-5.0/NOPB

    When thermal shutdown (or even temporary output short) the output voltage drops to something like 0.5V but the inductor and the associated capacitor get very hot and prevent the regulator from recovery even after a power cycle, or at least until the inductor…
