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?
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…
