Description
The AP3598A is a dual-phase synchronous buck PWM controller with integrated drivers which are optimized for high performance graphic card and computer applications. The IC is capable of delivering up to 60A output current capability, supporting 12V MOSFET drivers with internal bootstrap diodes.
The dynamic output voltage could be implemented by analog method with a switching device and a resistor network. The adjustable current balance is achieved by RDS(ON) current sensing technique.
The AP3598A provides over current protection, input/output under voltage protection, over voltage protection and over temperature protection.
Other features include adjustable soft start, adjustable operation frequency and so on. With aforementioned functions, the IC adopts U-QFN4040-24 package.
