SQ25821 Description
The SQ25821 is a stackable synchronous step-down converter which can operate in two modes. Mode I is a dual phase, single output synchronous step-down converter capable of delivering 30A output current in total. Mode II is a dual synchronous step-down converter capable of delivering 15A/15A output current each.
