PowerPAIR is an integrated MOSFET power stage for a synchronous buck converter. Combining TrenchFET Gen IV MOSFETs, this product portfolio provides exception values for improving performance, design form factors, and energy saving. The package layout provides excellent thermal path on the PCB for high current DC-DC converters. The integration approach reduces the parasitics generated by complex PCB traces. Using TrenchFET IV technology significantly reduces both conduction and switching losses. In a PowerPAIR 3x3, the benefit is more obvious in such a small package footprint. The power loss is reduced as much as 1.4 W in a 12 Vin to 1.8 Vout conversion. Lower power loss means the DC-DC conversion is more efficient and has the potential to handle higher power density and output current. The SiZ340DT outperforms the competitor’s devices with 18% less power loss.
