... Description The EV1340 is a Power System on a Chip (PowerSoC converter pin QFN that is optimized for DDR2, DDR3, and QDR VTT applications. It requires a power supply (AVIN) for the controller and operates from an input supply (VDDQ) voltage range of 1.0V to 1.8V and provides a tightly regulated and very ...

... NOTE: NC pins are not to be electrically connected to each other or to any external signal, ground, or voltage. However, they must be soldered to the PCB. Failure to follow this guideline may result in part malfunction or damage. ©Enpirion 2010 all rights reserved, E&OE Figure 3: Pin Out Diagram (Top View) 2 EV1340 Product Brief BGND ...

... AVIN1, 3.3V input supply. Decouple with a capacitor to AGND. AVIN2 POK is a logical AND of VDDQOK and the internally generated POK of the EV1340. POK is an open drain logic output that requires an external pull-up resistor. POK is logic high when VOUT is within -10% to POK +10% of VOUT nominal. This pin guarantees a logic low even when the EV1340 is completely un- powered. This pin can sink a maximum 4mA. The pull-up resistor may be connected to a power supply other than AVIN or VDDQ but the voltage should be < ...
