LM76003-Q1: Synchronizing two LM76003-Q1 to a LM70840, is this possible?

Conrad Seymour

Part Number: LM76003-Q1
Other Parts Discussed in Thread: LM76003, LM70840,

Tool/software:

We would like to have 3 power supplies running off 48V, creating 5V, 3.3V, and 24V. We were considering creating the 5V with a LM70840, starting up 1st, followed by the 3.3V and 24V using the LM76003-Q1. Could we synchronize the LM76003-Q1's to the LM70840? Could the two LM76003's run 180 deg out of phase with each other?

Hi,

The engineer in charge of this device is OOO and will be back next week. Please keep in mind Monday is US holiday so response will be delayed.

Thanks,

Richard

Hello Conrad,

the LM76003 has a synch in pin, and you can clock sync them how you like, as long as the clock sync is 180 degrees out of phase, then the converters will run out of phase accordingly, hope this helps.

David.
