Senpai Low Input Voltage POL Converters Deliver Full-Rated Output with No Thermal Derating

FDK Corporation (Tokyo Stock Exchange 1st Section: Code 6955) announced the latest products in its Senpai Series of non-isolated point of load (POL) converters with the addition of the FPLR05SR75 series of dc/dc converters. Operating from a 2.4Volt to 5.5Volt (V) DC input bus, these converters deliver up to 20 Amperes (A) of output current with best-in-class thermal performance: No derating is needed up to 85 degrees Celsius under natural convection. The Senpai Series dc/dc converters are designed for Intermediate Bus Architecture (IBA) and Distributed Power Architecture (DPA) applications that require high efficiency, tight regulation, and high reliability in elevated temperature environments with low airflow.

The FPLR05SR75 series converters are offered in 10A, 16A, and 20A output current models, in a 1.30x0.53x0.327 inch (33.0x13.4x8.3mm) SMD package with industry-standard footprint and pin-out. They provide tightly-regulated programmable output voltages in the range of 0.75V - 3.63V DC. All models feature remote ON/OFF, over-current and over-temperature protection, remote sense, and output voltage adjust, and are compatible with standard trim equations.

"The FPLR05SR75 series converters are a welcome addition to FDK's Senpai Series," said Dr. Apurba Roy, executive advisor, FDK Corporation. "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."

All Senpai Series products are RoHS compliant. They are manufactured using FDK's state-of-the-art in-house manufacturing processes and systems. In quantities of 1,000 pieces, the 10A, 16A, and 20A models are priced at $10.00, $12.00, and $15.00, respectively. Samples are available now.
