FEATURES  
DESCRIPTION  
The LM25116 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 current 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 applications. The  
operating frequency is programmable from 50 kHz to  
1 MHz. The LM25116 drives external high-side and  
low-side NMOS power switches with adaptive dead-  
time control. A user-selectable diode emulation mode  
enables discontinuous mode operation for improved  
efficiency at light load conditions. A low quiescent  
current shutdown disables the controller and  
consumes less than 10 µA of total input current.

Emulated peak current mode  
Wide operating range up to 42V  
Low IQ shutdown (< 10 µA)  
Drives standard or logic level MOSFETs  
Robust 3.5A peak gate drive  
Free-run or synchronous operation to 1 MHz  
Optional diode emulation mode  
Programmable output from 1.215V to 36V  
Precision 1.5% voltage reference  
Programmable current limit  
Programmable soft-start  
Programmable line under-voltage lockout  
Automatic switch to external bias supply  
HTSSOP-20 exposed pad  
Thermal shutdown  
Additional features include  
a high voltage bias  
regulator, automatic 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 HTSSOP-20 package  
featuring an exposed die attach pad to aid thermal  
dissipation.
