EM5303/A  
5V/12V Synchronous Buck PWM Controller  
General Description  
Applications  
EM5303/A is a synchronous rectified PWM  
controller operating with 5V or 12V supply voltage.  
This device operates at 200/300 kHz and provides  
an optimal level of integration to reduce size and  
cost of the power supply.
