DataSheeT power solutions EZ6303QI Triple Output Module 2.2A DC-DC Buck Module with 2 x 300mA LDOs The EZ6303QI is a triple output PowerSoC with one buck and two low drop-out LDO regulators. It has three separated inputs and outputs. The DC-DC buck can support up to 2.2A of continuous output current while the other two outputs are separated 300mA LDOs. The EZ6303QI employs Intel Enpirion’s lateral MOSFET technology for monolithic integration and very low switching loss. The DC-DC switches at 2.5MHz in fixed PWM operation to eliminate the low frequency noise that is created by pulse frequency modulation operating modes. The MOSFET ratios are optimized to offer high conversion efficiency for lower VOUT settings. The Intel Enpirion power solution significantly helps in system design and productivity by offering greatly simplified board design, layout and manufacturing requirements. In addition, a reduction in the number of vendors required for the complete power solution helps to enable an overall system cost savings. All Enpirion products are ROHS compliant and leadfree manufacturing environment compatible.
