Product details

DDR controller with 4.5V–23V input and dual 0.8V–3.6V outputs

The MAX8538EEI+: Its input range spans 4.5V to 23V, covering common 5V and 12V rails in computing and embedded systems. The two outputs are independently programmable from 0.8V up to 3.6V, which means a single device can supply both VTT at half the VDDQ level and a separate VREF at a different voltage — a configuration that serves DDR1 through DDR4 memory interfaces without changing the IC.

28-QSOP footprint and commercial temperature envelope

Packaged in a 28-lead SSOP with 0.154-inch body width, the MAX8538EEI+ also lists the supplier device package as 28-QSOP — these are the same mechanical footprint; QSOP is the tighter-pitch variant of SSOP with identical 3.90 mm width. For extended-temperature DDR power management, a different grade would be needed.

Frequently asked questions

Is MAX8538EEI+ suitable for DDR3 memory applications?

Yes. The MAX8538EEI+ is a DDR controller with an output voltage range of 0.8V to 3.6V. DDR3 VTT is 0.75× VDDQ (typically 1.35V or 1.5V), which falls well within this range. The two outputs can provide both VTT and VREF independently, meeting the DDR3 JEDEC power rail requirements.

Does MAX8538EEI+ require external components for a typical DDR controller circuit?

As a controller IC, the MAX8538EEI+ requires external MOSFETs, inductors, and capacitors to form the complete switching regulator that generates VTT and VREF from the input rail. The IC itself provides the control loop, error amplification, and reference generation — the power stage components are external and selected based on the output current requirement.
