PoL regulator at 4, 6, and 8 amps in compact low-profile package

Flex Power Modules' PMU8000 series point-of-load (PoL) converters have an excellent price/performance ratio and come in a compact, low-profile package (0.29" x 0.29" x 0.21" / 7.5 mm x 7.5 mm x 5.4 mm). These regulators offer high efficiencies up to 95.3% (12 V_IN / 5 V_OUT version) 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 0.29" x 0.29" x 0.21". 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 this 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 PMU8000 series 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.
