Key Features

The EV1320QI is a high-efficiency, compact power solution specifically designed for DDR memory termination applications. It operates directly from the VDDQ supply rail, eliminating the need for an external reference or divider. The device can source and sink up to 2A continuously, ensuring stable VTT voltage that precisely tracks half of VDDQ within ±40mV. Its programmable soft-start feature allows for controlled ramp-up, enhancing system reliability. With integrated protection mechanisms—including over-current, short-circuit, under-voltage lockout, and thermal shutdown—the EV1320QI safeguards against various fault conditions. Its high switching frequency of 750 kHz enables the use of small external components, contributing to a total solution size of approximately 40mm². The device’s efficiency reaches up to 96%, making it suitable for energy-conscious applications. Housed in a 16-pin QFN package measuring 3mm x 3mm x 0.55mm, the EV1320QI is ideal for space-constrained designs.

Applications

VTT bus termination for DDR2, DDR3, DDR4, low-power DDR3, DDR4, and QDR memories
High-efficiency memory termination in computing and networking equipment
Compact power solutions in portable and embedded systems
Systems requiring precise voltage tracking and high current sourcing/sinking capabilities
Applications demanding robust protection features and high reliability

Product Overview

The EV1320QI offers a robust and efficient solution for memory termination needs in modern electronic systems. Its design simplifies power architecture by operating directly from the VDDQ supply, eliminating the complexity of additional reference voltages. The device’s ability to source and sink substantial current ensures that the termination voltage (VTT) remains stable, a critical factor for the reliable operation of high-speed memory interfaces. The programmable soft-start feature allows designers to tailor the power-up sequence to specific system requirements, enhancing overall reliability. Integrated protection features provide safeguards against common fault conditions, ensuring long-term durability. The compact QFN package and minimal external component requirements make the EV1320QI an excellent choice for applications where board space is at a premium. Its high efficiency not only reduces power consumption but also minimizes heat generation, benefiting both performance and energy efficiency.
