FEATURES  
DESCRIPTION  
The LM5118 wide voltage range Buck-Boost  
switching regulator controller features all of the  
functions necessary to implement high  
2
LM5118-Q1 is an Automotive Grade product  
that is AEC-Q100 grade 1 qualified (-40°C to  
125°C operating junction temperature)  
a
performance, cost efficient Buck-Boost regulator  
using a minimum of external components. The Buck-  
Boost topology maintains output voltage regulation  
when the input voltage is either less than or greater  
than the output voltage making it especially suitable  
for automotive applications. The LM5118 operates as  
a buck regulator while the input voltage is sufficiently  
greater than the regulated output voltage and  
gradually transitions to the buck-boost mode as the  
input voltage approaches the output. This dual mode  
approach maintains regulation over a wide range of  
input voltages with optimal conversion efficiency in  
the buck mode and a glitch-free output during mode  
transitions. This easy to use controller includes  
drivers for the high side buck MOSFET and the low  
side boost MOSFET. The regulators control method  
is based upon current mode control utilizing an  
emulated current ramp. Emulated current mode  
control reduces noise sensitivity of the pulse-width  
modulation circuit, allowing reliable control of the very  
small duty cycles necessary in high input voltage  
applications. Additional protection features include  
current limit, thermal shutdown and an enable input.  
Ultra-wide input voltage range from 3V to 75V  
Emulated peak current mode control  
Smooth transition between step-down and  
step- up modes  
Switching frequency programmable to 500KHz  
Oscillator synchronization capability  
Internal high voltage bias regulator  
Integrated high and low-side gate drivers  
Programmable soft-start time  
Ultra low shutdown current  
Enable input wide bandwidth error amplifier  
1.5% feedback reference accuracy  
Thermal shutdown  
PACKAGE  
HTSSOP-20 (Exposed pad)  
The device is available in  
a power enhanced  
HTSSOP-20 package featuring an exposed die attach  
pad to aid thermal dissipation.
