PMU8000 series of Point-of-Load (PoL) converters provide an excellent price/performance ratio in a compact, low-profile package. The new regulators offer high efficiency of typically 95.3 % (at half load) and excellent thermal performance, meaning they can be used in harsh conditions.
The ultra-miniature 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.
To save substantial space, the regulators are provided in a very small form factor package, measuring just 7.5 x 7.5 x 5.4 mm. They support bottom side assembly, which means that a customer can utilize this design capability to make further significant space savings.
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 new PoL regulators are well-suited to a wide 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 (IoT), railway and medical.
The new regulators achieve exceptionally high levels of reliability with MTBF figures of up to 172 Mhrs, and meet safety requirements according to the IEC/EN/UL62368-1 standard.
