DataSheeT enpirion power solutions EN6310QA 1A PowerSoC Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION FEATURES The EN6310QA is a member of Intel Enpirions high Integrated inductor, MOSFET and Controller efficiency EN6300 family of PowerSoCs. The -40C to 105C Ambient Temperature Range EN6310QA is a 1A PowerSoC that is AEC-Q100 AEC-Q100 Qualified for Automotive Applications qualified for automotive applications. The EN6310QA employs Intel Enpirions EDMOS Small 4mm x 5mm x 1.85mm QFN MOSFET technology for monolithic integration and High Efficiency up to 96% very low switching loss. The device switches at 2 Solution Footprint Less than 65mm 2.2MHz in fixed PWM operation to eliminate the low 1A Continuous Output Current frequency noise that is created by pulse frequency VIN Range of 2.7V to 5.5V modulation operating modes. The MOSFET ratios are optimized to offer high conversion efficiency for VOUT Range from 0.6V to 3.3V lower VOUT settings. Programmable Soft Start and Power OK Flag Output voltage settings are programmable via a Fast Transient Response and Recovery Time simple resistor divider circuit. Output voltage can be Low Noise and Low Output Ripple 4mV Typical programmed from as low as 0.6V to 3.3V. The device 2.2MHz Switching Frequency has a programmable soft-start ramp rate to accommodate sequencing and to prevent un-wanted Under Voltage Lock-out (UVLO), Short Circuit, Over current inrush at start up. A Power OK (POK) flag is Current and Thermal Protection provided to indicate a fault condition. The Intel Enpirion power solution significantly helps APPLICATIONS in system design and productivity by offering greatly Automotive Applications simplified board design, layout and manufacturing Altera FPGAs (MAX, ARRIA, CYCLONE, requirements. In addition, a reduction in the number STRATIX) of vendors required for the complete power solution Low Power FPGA Applications helps to enable an overall system cost savings. Noise Sensitive Wireless and RF Applications All Intel Enpirion products are RoHS compliant and lead-free manufacturing environment compatible.
