NCP12700  
Ultra Wide Input Current  
Mode PWM Controller  
The NCP12700 is a fixed frequency, peak current mode, PWM  
controller containing all of the features necessary for implementing  
single−ended power converter topologies. The device features a high  
voltage startup capable of operating over a wide input range and  
www.onsemi.com  
supplying at least 15 mA to provide temporary bias to V during  
CC  
system startup. The device contains a programmable oscillator  
capable of operating from 100 kHz to 1 MHz and integrates slope  
compensation to prevent subharmonic oscillations. The controller  
offers an adjustable soft−start, input voltage UVLO protection, and an  
adjustable Over−Power Protection circuit which limits the total power  
capability of the circuit as the input voltage increases, easing the  
system thermal design. The UVLO pin also features a shutdown  
comparator which allows for an external signal to disable switching  
and bring the controller into a low quiescent state.

MARKING DIAGRAMS  
The NCP12700 contains a suite of protection features including  
cycle−by−cycle peak current limiting, timer−based overload  
protection, and a FLT pin which can be interfaced with an NTC and an  
auxiliary winding to provide system thermal protection and output  
over−voltage protection. All protection features place the device into a  
low quiescent fault mode and recovery from fault mode is dependent  
on the device option.
