Boost converter for automotive battery rails
It steps up from an input as low as 0.9 V to an adjustable output up to 5.5 V, with a 1.8 A switch current rating and 600 kHz fixed switching frequency.
Input range and output capability
The 0.9 V minimum input lets this part run from a single-cell alkaline, NiMH, or Li-ion battery near its end-of-discharge voltage. Synchronous rectification keeps efficiency above 90% across much of the load range, reducing heat in the 10-VSON package with exposed pad — a real advantage in sealed automotive modules with limited airflow.
For new automotive designs this means no supply-chain risk from a looming phase-out.
