SNVSAX9 – JUNE 2017 LM5118-Q1 Wide Voltage Range Buck-Boost Controller
1 Features 3 Description The LM5118-Q1 wide voltage range Buck-Boost
switching regulator controller features all of the
functions necessary to implement a highperformance, cost-efficient Buck-Boost regulator
using a minimum of external components. The BuckBoost 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-Q1
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 …
