The SY26132 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. Two SY26132 devices can be paralleled together to provide up to 60A capability.

 The SY26132 operates over a wide input voltage range from 3.0V to 16V and integrates main switches and synchronous switches with very low R_DS(ON). The interleaving operating of the SY26132 reduces the input and output capacitance. The device also integrates the PMBus 1.3 compatible interface for mode selecting, output voltage setting, input UVLO threshold setting, protection setting, etc. Besides, the device implements measurement system to monitor the output voltages, currents and temperatures for individual channels.

The device is available in compact LGA6´6-42 package.
