EV1320QI-E Datasheet PDF - Enpirion

●EV1320QI-E is an evaluation board for EV1320QI, 2A source/sink high efficiency VTT converter for DDR2/DDR3/QDR and low voltage DDR4 Memory Termination Voltage Applications. The EV1320 is an ideal source/sink DDR termination converter offering excellent performance with low cost and a tiny solution footprint. EV1320 solutions deliver nearly 2 times the efficiency at or below the cost of commonly used VTT LDOs. The VTT converter accepts an input voltage of 0.95V to 1.8V. Multiple EV1320 devices may be placed in parallel to support larger DDR memory capacities (higher load requirements). EV1320 is a purpose built VTT converter solution that complies with JEDEC specifications, in particular tracking accuracy and AC + DC requirements for supporting DDR2/DDR3/QDR and low power DDR3/DDR4 VTT applications.

● Operates directly from VDDQ, Low Vin from 0.95V to 1.8V

● Output VTT precisely tracks ½ VDDQ voltage

● Small 40mm2 solution area, with 0.55mm low profile

● No external inductor required

● Ultra high 96% efficiency

● Parallel up to 4 devices for 8A VTT load current

● Enable pin with output discharge to support S3 (suspend to RAM) mode

● Programmable soft start time, soft shutdown

● Thermal overload, over current, short circuit and under voltage protection

● High reliability

●Be mindful of the polarity and magnitude. This evaluation board has no reverse polarity or voltage clamping protection on it.
