POL regulators allow more design flexibility

Ericsson Power Modules has expanded its interoperable POLA series of point of load regulators with an additional 17 products all intended for use in distributed power architectures.

Ericsson Power Modules has expanded its interoperable POLA series of point of load (POL) regulators with an additional 17 products all intended for use in distributed power architectures.

Offering secure sourcing and commonality of product specifications for ease of purchasing, three POL platforms have been introduced.

For use in different application areas, the product platforms embrace current ratings from 6 to 60A, and most products are available with 3.3, 5 and 12V input capability.

The products are aimed at OEM and CEM customers with applications in communications, avionics, industrial and medical equipment.

The POL regulators provide a good fit with customers demanding multiple sources and design flexibility due to the number of vendors providing the same products within Point Of Load Alliance (POLA), and the wide range of platforms that will suit most power requirements.

Enabling system builders to reduce costs, all products feature an open frame, reduced manufacturing cost design.

Designed for use in applications with DDR and QDR memory chips where a tightly controlled termination voltage is needed, nine new regulators are able to generate a termination voltage (VTT) with a +/-40mV tolerance compared with the reference VDDQ.

The DDR/QDR series of POL regulators is available in three different power levels: PME-V for 6A, PMF-V for 10A and PMG-V for 15A versions.

All are available in through hole and surface mount versions.

By maximising power density to enable a minimised footprint thus saving board space, six single inline (SIP) products for 8A - PMK and 18A - PML have been introduced.

Equipped with the aforementioned input voltages, on all versions the output voltage can be set to any value between 0.8 and 5.5V.

The SIP platform has a higher power density and more features then other well-known footprints on the market.

As high current, nonisolated POL convertors suitable for servers and current thirsty high-end computer applications, the PMM family of products is available in two input voltage variants, 3.0-5.5 and 8-14V.

The parts can deliver up to 60A of output current with an efficiency peak of 96%.

The output voltage can be externally configured by a chip resistor to any value between 0.8 and 5.5V.

Again the regulators are available in both through hole and surface mount versions.

The PMM regulators use an innovative three-phase design for optimum performance, and for tight voltage control they use a differential output sense feature.

The platform is unique due to its high power density combined with a high efficiency figure of 96%.

POL regulators allow for more design flexibility where there are many voltages in the same system.

Also driving the demand for these products are complex circuits like ASICs and DSPs that demand power sequencing.

Additionally, customers now demand multiple sourcing, and this trend has driven the industry to form alliances and standards; POLA being the first alliance that offers completely interoperable DC/DC products.

This latest range of POLA interoperable regulators from Ericsson Power Modules offers many options in terms of power, size and voltages, and their high efficiency offers increased reliability and system lifetime costs.

Advanced features include power sequencing via an auto-track control, capability to start up into a prebiased output, wide adjustment range, thermal shutdown, output sense and inhibit control.
