Datasheet Summary
AX5520/1
20A Fully Integrated Synchronous Boost Converter
GENERAL DESCRIPTION
The AX5520/AX5521 is a high efficiency fully integrated synchronous Boost converter with built-in main switch and synchronous switch. The device has 20A switch peak current capability and provides output voltage up to 18V(AX5520) or 30V(AX5521). Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, allowing the AX5520/ AX5521 to be used in high power step-up applications. The 2.7V to 18V(MT AX5520) or 30V(AX5521) input voltage range supports a wide range of battery and AC powered inputs. The 70µA no load quiescent current extends operating run time in battery-powered...
