ADT7350
General Description
The ADT7350 is a step-down converter with
integrated switching MOSFET. It operates wide
input supply voltage range from 4.5V to 24V with
1.2A peak output current. It includes current
limiting protection and thermal shutdown.
It reduces design complexity and external
component count. The ADT7350 is available in
small outline SOT23-6L package.
