LM25118Q1MHX Integrated Circuit Chip
Wide Voltage Range Buck-Boost Controller HTSSOP20
The LM25118Q1MHX is a wide voltage range buck-boost switching regulator controller that provides all necessary functions for implementing high-performance, cost-efficient buck-boost regulators with minimal external components.
Product Overview
This controller operates as a buck regulator when input voltage significantly exceeds the regulated output voltage, gradually transitioning to buck-boost mode as input voltage approaches output. This dual-mode approach maintains regulation across wide input voltage ranges while optimizing conversion efficiency in buck mode and ensuring glitch-free output during mode transitions.
