20-A POL DC/DC converter operates from a 3.5-V to 14-V bus

TDK Corp. has announced the introduction of the 20-A TDK-Lambda iBH series of POL (point of load) nonisolated DC/DC converters. Accepting an input range of 3.5 to 14 VDC, the series can operate from either a 5-VDC or 12-VDC bus.

The iCH series can provide output voltages from 0.7 to 5.5 V, with efficiencies of up to 96%. Capable of delivering up to 80 W, the converters can operate in high-ambient-temperature, low-airflow environments with minimal power derating. The series is designed to meet a range of applications, including servers, routers, and other information and communication technology (ICT) equipment; semiconductor manufacturing equipment; measuring equipment; and general industrial equipment.

The surface-mount converters occupy just 0.36 square inches of board space, measuring 0.8 x 0.45 x 0.39 inches (20.3 mm x 11.4 mm x 9.9 mm) with a weight of just 6 g. As with all TDK-Lambda’s DOSA compatible footprint POLs, the iBH does not need externally mounted loop-tuning components and has excellent transient response to load changes.

Product features include output trim adjustment, power good, remote sense, and a choice of positive or negative logic remote on/off. Full protection, with auto-recovery, is provided against input under-voltage, output short circuit, and over-temperature. All models are certified to UL/CSA 60950-1, IEC/EN 60950-1 and carry the CE mark for the low voltage and RoHS2 directives.
