DataSheeT enpirion power solutions EZ6303QI Triple Output Module 2.2A DC-DC Buck Module with 2 x 300mA LDOs DESCRIPTION FEATURES Integrated 2.2A Buck Module with 2x300mA LDO The EZ6303QI is a triple output PowerSoC with one buck and two low drop-out (LDO) regulators. It has Tiny 7mm x 4mm x 1.85mm QFN Package three separated inputs and outputs. The DC-DC buck High Efficiency Buck (Up to 96 %) can support up to 2.2A of continuous output current 2 Optimized Total Solution Size (120 mm ) while the other two outputs are separated 300mA Input Voltage Range LDOs. o Buck (2.7V to 3.6V) The EZ6303QI employs Intel Enpirions lateral o LDO (1.6V to 3.6V) MOSFET technology for monolithic integration and Output Voltage Range very low switching loss. The DC-DC switches at 2.5MHz in fixed PWM operation to eliminate the low o Buck (0.6V to 3.0V) frequency noise that is created by pulse frequency o LDO (0.9V to 3.3V) modulation operating modes. The MOSFET ratios are Independent Input and Output Terminals optimized to offer high conversion efficiency for Independent Output Enables and Power OK Flags lower VOUT settings. Programmable Soft-Start (buck) The Intel Enpirion power solution significantly helps Over-Current, Short Circuit, Under-Voltage, in system design and productivity by offering greatly Thermal and Pre-Bias Protections simplified board design, layout and manufacturing Pin Compatible with EZ6301QI requirements. In addition, a reduction in the number of vendors required for the complete power solution RoHS Compliant, MSL Level 3, 260 C Reflow helps to enable an overall system cost savings. APPLICATIONS All Enpirion products are ROHS compliant and lead- Intel FPGAs (MAX, ARRIA, CYCLONE, STRATIX) free manufacturing environment compatible.
