20A DOSA POL Operates from a 3.5V to 14V Bus
TDK Corporation announces the introduction of the 20-Amp TDK-Lambda iBH series of POL (Point of Load) non-isolated dc-dc converters. Accepting a wide range input of 3.5- to 14-Vdc, the series can operate from either a 5-Vdc or 12-Vdc bus.
The iBH series can provide output voltages from 0.7- to 5.5-V, with efficiencies of up to 96%. Capable of delivering up to 80W, the converters can operate in high ambient temperature, low airflow environments with minimal power derating. The series is designed to meet a wide 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 0.36 square inches of board space, measuring 0.8 x 0.45 x 0.39 inches (20.3mm x 11.4mm x 9.9mm) with a weight of 6g. 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.
