Product Overview

The LTC3618EFE#PBF is a dual synchronous Step-Down Regulator using a current mode, constant-frequency architecture. It provides a complete DDR solution with an input voltage range from 2.25 to 5.5V. The output of the first step-down regulator offers a high accuracy VDDQ supply. A buffered reference generates VTTR at 50% of VDDQIN and drives loads up to ±10mA. The second regulator generates the DDR termination voltage (VTT) equal to VTTR. Both regulators are capable of delivering ±3A of load current at 1MHz switching frequency. The operating frequency is externally programmable up to 4MHz, allowing the use of small surface mount inductors. 0, 90 or 180° of phase shift between the two channels can be selected to minimize input current ripple. For switching noise-sensitive applications, the LTC3618 can be synchronized to an external clock up to 4MHz.
