The AP6502A features current mode control operation, which enables  
fast transient response times and easy loop stabilization.  
The AP6502A 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.  
SO-8EP
