DESCRIPTION
Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization. Under voltage lockout is internally set as 4.6 V, An open drain power good signal indicates the output is within its nominal voltage range. Full protection features include OCP, OVP, and thermal shut down. The converter requires minimum number of external components and is available in QFN16 (3mmx3mm) package.
