FDK's FPLR05SR75 series of DC/DC converters

FDK Corp. has added the FPLR05SR75 series of DC/DC converters to its Senpai family of non-isolated POL converters.

Operating from a 2.4-5.5V DC input bus, these converters deliver up to 20A of output current with efficient thermal performance: no derating is needed up to 85C under natural convection. Senpai devices are designed for intermediate bus architecture and distributed power architecture applications that require high efficiency, tight regulation and high reliability in elevated temperature environments with low airflow.

The FPLR05SR75 series converters offer 10-, 16- and 20A output current options, in a 33-by-13.4-by-8.3mm SMD package with industry-standard footprint and pin-out. "Delivering up to 20A with no derating in this small size, FDK is setting new standards for point-of-load power availability in high temperature and high density applications," said Apurba Roy, executive advisor, FDK Corp.

The new products provide tightly regulated programmable output voltages in the range of 0.75-3.63Vdc. All models feature remote ON/OFF, overcurrent and over-temperature protection as well as remote sense and output voltage adjust, and are compatible with standard trim equations.

The products under the Senpai series product line are manufactured using FDK's in-house manufacturing processes and systems. All the products are RoHS-compliant. Samples are available today. The 10-, 16- and 20A models are priced at $10, $12 and $15, respectively, in quantities of 1,000 pieces.
