TSOT26 LIGHT LOAD IMPROVED 1.5A SYNCH DC-DC BUCK CONVERTER
The AP65111 is an internally compensated synchronous DC-DC buck
converter with a 500kHz switching frequency. It is integrated with high
and low-side MOSFETs with low RDS(ON).
The AP65111 enables continuous load current of up to 1.5A with
efficiency as high as 97%.
The AP65111 implements an automatic custom light-load efficiency
The AP65111 features current mode control operation, which enables
fast transient response times and easy loop stabilization.
The AP65111 simplifies board layout and reduces space
requirements with its high level of integration and minimal need for
external components, making it ideal for distributed power
The AP65111 is available in a standard Green TSOT26 package and
is RoHS compliant.
