Dear TI community,
From a single DC bus, I want to generate 2 outputs using two boost converters using the LM3488 controller, both at 550 kHz.
- Should I synchronise their switching?
- If so, how should I generate the external clock signal? Obviously, the cheapest solution, the better. Schmidt trigger, 555 oscillator, Pierce oscillator, or ... ?
Thanks, and regards,
Hugues
