enpirion®功率表en2342qi 4a功耗SoC电压模式同步PWM降压集成电感

　　The EN2342QI is a Power System on a Chip （PowerSoC） DC-DC converter. It integrates MOSFET switches， small-signal control circuits， compensation and an integrated inductor in an advanced 8x11x3mm QFN module. It offers high efficiency， excellent line and load regulation over temperature and up to the full 4A load range. The EN2342QI operates over a wide input voltage range and is specifically designed to meet the precise voltage and fast transient requirements of high-performance products. The EN2342 features frequency synchronization to an external clock， power OK output voltage monitor， programmable soft-start along with thermal and over current protection. The device’s advanced circuit design， ultra high switching frequency and proprietary integrated inductor technology delivers high-quality， ultra compact， non-isolated DC-DC conversion. The Altera Enpirion solution significantly helps in system design and productivity by offering greatly simplified board design， layout and manufacturing requirements. In addition， overall system level reliability is improved given the small number of components required with the Altera Enpirion solution. All Altera Enpirion products are RoHS compliant， halogen free and are compatible with lead-free manufacturing environments.
