NCP1561  
Push−Pull PWM Controller  
for 48 V Telecom Systems  
The NCP1561 Push−Pull PWM controller contains all the features  
and flexibility needed to implement high efficiency dc−dc converters  
using voltage or current−mode control. This device can be configured  
in any dual ended topology such as push−pull or half−bridge. It can  
also be used for forward topologies requiring a 50% maximum duty  
cycle. This device is ideally suited for 48 V telecom, 42 V automotive  
systems and 12 V input applications.  
The NCP1561 cost effectively reduce system part count by  
incorporating a high voltage startup regulator, line undervoltage  
detector, single resistor oscillator setting, dual mode overcurrent  
protection, soft−start and single resistor feedforward ramp generator.  
The oscillator frequency can be adjusted up to 250 kHz.
