LM2663: LM2663MX alternative

HS FAE Germany

Part Number: LM2663
Other Parts Discussed in Thread: LM2660, TL7660

Hi,
customer uses the LM2663MX and is searching for a ptp alternative. May be the LM2660 would work but in his current design the pin 1 is connected GND. Woudl that work with the LM2660?
Then may be the TL7660 would be a better fit?

Regards, Holger

Hello Holger,

Connecting FC to GND works with the LM2660 if LV is as well connected to GND and then the converter will switch with 10kHz.

Best regards,
Brigitte

Hi Brigitte,
unfortunately customer didn't connect the LV to GND. What do you think about the TL7660 as an alternative?

Hello Holger,

TL7660 has an NC pin on pin 1, so the customer can have GND connected to pin 1.

Best regards,
Brigitte
