Still the IC is just getting hot and only outputting mV. No, create an account now.

LM2675 – LM2675 1A Step-Down Voltage Regulator Datasheet

The capacitor values are much bigger than those suggested for input and output by the data sheet. Apr 26, 8.

Yes, my password is: I followed the instructions in the LM datasheet. I am using the following parts: Table 3, page 15, datashert a table for selecting the output capacitor, and pages following that discuss the input capacitor. Apr 26, 1. I am trying to convert from 12v to 6v.
