Hi,

I simulate with LT3589 macromodel test fixture in LTspice.

It seems SW4 switching frequency is 1.12MHz.

I think SW4 work not by 1.12MHz, but by 2.25MHz.

Would you confirm it?

Hi,

I am designing the power section for a Texas Instrument omap-l138, and I want to use the LTC3589.

After LDO4 is enabled, I want to write the  register L2DTV2 bit(6:5)  to change voltage on LDO4 from 2.8v to 3.3v. Is it going to glitch the PGOOD output…
