LM5116  
Wide Range Synchronous Buck Controller  
General Description  
Features  
The LM5116 is a synchronous buck controller intended for  
step-down regulator applications from a high voltage or widely  
varying input supply. The control method is based upon cur-  
rent mode control utilizing an emulated current ramp. Current  
mode control provides inherent line feed-forward, cycle by  
cycle current limiting and ease of loop compensation. The use  
of an emulated control ramp reduces noise sensitivity of the  
pulse-width modulation circuit, allowing reliable control of  
very small duty cycles necessary in high input voltage appli-  
cations. The operating frequency is programmable from  
50kHz to 1MHz. The LM5116 drives external high-side and  
low-side NMOS power switches with adaptive dead-time con-  
trol. A user-selectable diode emulation mode enables discon-  
tinuous mode operation for improved efficiency at light load  
conditions. A low quiescent current shutdown disables the  
controller and consumes less than 10µA of total input current.  
Additional features include a high voltage bias regulator, au-  
tomatic switch-over to external bias for improved efficiency,  
thermal shutdown, frequency synchronization, cycle by cycle  
current limit and adjustable line under-voltage lockout. The  
device is available in a power enhanced TSSOP-20 package  
featuring an exposed die attach pad to aid thermal dissipation.
