Description
The EV1340 is a Power System on a Chip (PowerSoC) DC to DC converter in a 54 pin QFN that is optimized for DDR2, DDR3, and QDRTM VTT applications. It requires a nominal 3.3V power supply (AVIN) for the controller, and an input supply (VDDQ) voltage range of 1.0V to 1.8V. It provides a tightly regulated and very stable output voltage (VTT) which tracks VDDQ while sinking and sourcing up to 5A of output current. In addition, the EV1340 is an excellent solution for general low VIN applications where high efficiency is critical.
