DataSheeT enpirion power solutions EN2342QI 4A PowerSoC Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION FEATURES Integrated Inductor, MOSFETs, Controller The EN2342QI is a Power System on a Chip Wide Input Voltage Range: 4.5V 14V (PowerSoC) DC-DC converter. It integrates MOSFET switches, small-signal control circuits, compensation Guaranteed 4A I at 85C with No Airflow OUT and an integrated inductor in an advanced Frequency Synchronization (External Clock) 8x11x3mm QFN module. It offers high efficiency, 1.5% V Accuracy (Over Load and Temperature) OUT excellent line and load regulation over temperature High Efficiency (Up to 95%) and up to the full 4A load range. The EN2342QI Output Enable Pin and Power OK signal operates over a wide input voltage range and is Programmable Soft-Start Time specifically designed to meet the precise voltage and fast transient requirements of high-performance Pre-Bias Protection products. The EN2342QI features frequency Pin Compatible with the EN2340QI synchronization to an external clock, power OK Under Voltage Lockout Protection (UVLO) output voltage monitor, programmable soft-start Thermal Soft-Shutdown Protection along with thermal and over current protection. The Over Current and Short Circuit Protection devices advanced circuit design, ultra high switching o RoHS Compliant, MSL Level 3, 260 C Reflow frequency, integrated inductor technology delivers high-quality, and non-isolated DC-DC conversion. APPLICATIONS Intel Enpirion Power Solutions significantly help in FPGA Applications, Core, IO, Transceiver system design and productivity by offering greatly Space Constrained Applications simplified board design, layout and manufacturing Output Voltage Ripple Sensitive Applications requirements. In addition, overall system level Beat Frequency Sensitive Applications reliability is improved given the small number of Servers, Embedded Computing Systems, LAN/SAN components required with Intel Enpirion solution.
