Flex Power Modules has launched a series of Point-of-Load (PoL) regulators in a compact, low-profile package that handle from 4 to 8A of current.

The PMU8000 series has an efficiency of typically 95.3 percent at half load and the thermal performance means they can be used in harsh conditions. To save substantial space, the regulators are provided in a small form factor package measuring 7.5 x 7.5 x 5.4 mm. They support bottom side assembly, which means that a customer can use this design capability to make further significant space savings.

The PoL regulators include a loop optimization feature, which enables design engineers to optimize their load transient response for different capacitive loads, thus increasing flexibility in system design. They also provide a configurable soft start or tracking feature, which makes time sequence design easier and more flexible.

There are three variants in the new series, each offering different maximum output currents. The PMU8218 provides an output up to 4 A / 22 W, the PMU8318 up to 6 A / 33 W, and the PMU8418 up to 8 A / 44 W. Each device has an output voltage range of 0.6 V to 5.5 V, and an input voltage range of 4.5 V to 17 V.

The PoL regulator family is aimed at applications such as including providing power for FPGAs, ASICs, Network Processors, CPUs and GPUs, across multiple sectors including ICT (telecom and datacom), industrial, test and measurement, Internet of Things (IoT), railway and medical.

“By using automatic production processes, we have been able to achieve high quality and lower component costs for the new PMU8000 regulators – giving our customers the reliability, efficiency and affordability they demand,” said Olle Hellgren, Director of Product Management and Business Development at Flex Power Modules.

The PoL regulator family has MTBF figures of up to 172 Mhrs, and meet safety requirements according to the IEC/EN/UL62368-1 standard.
