The AN6550 is a dual operational with a phase compensation and low voltage operation mode ....the question is ...are u constricted by the low voltage usage mode ? or not .I found those ....surfing and as i see there are some goodies bonus ....slew rate and so on ....didn't checked the equivalence but this worths to be seen.
