Hi there,
I am in search of a low-power SIMO PMIC, featuring a minimum of 3 SIMO outputs, with Dynamic Voltage Scaling capability for at least one output - which would have to be settable as low as 0.65V.
I have built a candidate shortlist: MAX77675, MAX77643, MAX77658.
However, among these, only the MAX77675 is explicitly specified for dynamic voltage changes, with slew rate and latency figures present in the datasheet.
Questions:
(1) Does that mean the other 2 don't support DVS ? Meaning, target voltage can only be set at power-up ? Or, meaning slew-rate / latency / possible over- or undershoots in case of dynamic changes of voltage settings are uncharacterized/unpredicable ?
(2) Any other MPN suggestions that could fit my requirements — essentially 3+ output SIMO with DVS support ?
Thanks -
