Overview

Enpirion's EC7401QI 4-Phase Pulse-Width Modulation (PWM) Controller drives up to four synchronous-rectified step-down channels in parallel. The EC7401QI paired with Enpirion ET4040QI 40A powertrain is recommended for high-power applications requiring high efficiency and tight accuracy such as FPGA core rails. It supports an 8 bit VID input with selectable VR11 digital-to-analog converter (DAC) code and extended VR10 DAC code at 6.25mV per bit. The EC7401QI offers precision current sensing which provides the needed signals for precision droop, channel-current balancing, and over-current protection. This PWM controller implements a programmable internal temperature compensation function to effectively compensate for the temperature coefficient of the current sense element. This controller is capable of 2-, 3-, or 4-phase operation. Designing with both the EC7401QI and ET4040QI addresses the needs of increasingly higher core power requirements for high-performance FPGAs.
