Part Number: LM2673 Hi Team,
Our customer designed a board with LM2673 to convert 12V to 5V, 3A. The output voltage of the board is 10V instead of 5V. The schematic diagram looks good but it seems the caused of the problem is the board layout.
Can you…
Part Number: LM2673 I have a question regarding the LM2673's Current Adjust pin. Below are two different configurations for the LM2673, one to output a positive voltage, and one to output a negative voltage. The regulator has a current limit adjust pin…
Part Number: LM2673 I know LM2673S-ADJ/NOPB(DDPAK/TO-263) is RoHS Exempt device.
Do you have a plan to release RoHS corresponded device after RoHS exemption expiring ?

Part Number: LM2673 Need help with Positive to Negative design.
I've read AN-1157. The schematic, Fig. 6, shows one end of the Iadj resistor and Css (softstart) capacitor connected to -Out. It seems if connected this way that the varying output of -Out…
Part Number: LM2673 Hi,
If the load is short-circuited (due to mis-wiring or water drops or dust adhering to the load side during operation) and the load impedance during short-circuit assumes about 0.2Ω,
(1) Calculate simply, the short-circuit…
Part Number: LM2673 I'm developing a voltage regulator circuit that outputs a positive and negative voltage using the LM2673, and I'm including current sensing in order to limit the current coming from both channels. After some trial and error, I managed…
Part Number: LM2673 Hi team, My customer is asking us about current limit function of LM2673 as below. 1. How long delay can be expected from over current detection to turn-off the high-side FET? I believe this should include response time of current detection…
