AP65211A

NEW PRODUCT NOT RECOMMENDED FOR NEW DESIGN CONTACT US AP65211A TSOT26 LIGHT LOAD IMPROVED 2A SYNCH DC-DC BUCK CONVERTER Description The AP65211A is a 500kHz switching frequency internal compensated synchronous DC-DC buck converter. It has integrated low RDS(ON) high and low side MOSFETs. The AP65211A enables continuous load current of up to 2A with efficiency as high as 97%. The AP65211A implements an automatic custom light load efficiency improvement algorithm. The AP65211A features current mode control operation, which enables fast transient response time and easy loop stabilization. The AP65211A 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. The AP65211A is available in a standard Green TSOT26 package and is RoHS compliant.
