AP65111WU-7

AP65111 TSOT26 LIGHT LOAD IMPROVED 1.5A SYNCH DC-DC BUCK CONVERTER Description Pin Assignments 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). Top View 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 improvement algorithm. The AP65111 features current mode control operation, which enables fast transient response times and easy loop stabilization. IN 1 6 FB GND 2 5 EN SW 3 4 BST 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 architectures. TSOT26 The AP65111 is available in a standard Green TSOT26 package and is RoHS compliant.
