Ultra-miniature PoL regulators from 4-8A take on tough conditions

New miniature regulators from Flex Power Modules offer high efficiency of typically 95.3 per cent (at half load) and a thermal performance for use in harsh conditions.

The PMU8000 series of Point-of-Load (PoL) converters include a loop optimisation feature, which enables design engineers to optimise their load transient response for different capacitive loads, to increase flexibility in system design. The also provide a configurable soft start or tracking feature, which the company says makes time sequence design easier and more flexible.

Provided in a small form factor package, measuring 7.5 x 7.5 x 5.4 mm, the regulators support bottom side assembly to help customers save space.

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

The regulators suit a range of power conversion applications, 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 railway and medical.

Olle Hellgren, director of product management and business development at Flex Power Modules, said: “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.”

The new regulators achieve high levels of reliability with MTBF figures of up to 172 Mhrs, and meet safety requirements according to the IEC/EN/UL62368-1 standard.

The PMU8318 is available now, and the PMU8218 and PMU8418 will be available in Q4.
