Description

The ACE73655Y is a monolithic, step down, switch mode converter with internal power MOSFETs. It

can provide continuous output current up to 6A from 2.8V to 5.5V input voltage, and has good load and

line regulation capability. The output voltage can be adjusted below 0.6V.

Constant on time control provides a fast-transient response and simplifies loop stability. Fault state

protections include cycle-by-cycle current limiting and thermal shutdown.

The ACE73655Y is housed in a small QFN2*3-12 package and requires only a minimal number of readily

available, standard, external components.
