TDK-Lambda announces 500W DC-DC buck step-down convertersERT

TDK Corporation announces the introduction of the TDK-Lambda i7A series of 33A 500W rated non-isolated DC-DC converters, packaged with the industry-standard 1/16th brick pinout. The output voltage of these step-down converters can be adjusted from 3.3 to 24V and accept a wide range input voltage of 18 to 60V.

The i7A 33A series can be used to derive additional high-power outputs from a 24V, 36V or 48V DC power supply, at a much lower cost than isolated DC-DC converters. These compact products are suited for use in medical, communications, industrial, test and measurement, broadcast and portable battery-powered equipment.

Efficiencies of up to 98% minimise internal losses and allow the i7A to operate in ambient temperatures of -40°C to +125°C, even with low airflow conditions.

A choice of three mechanical configurations is available

Standard features for the i7A series include an output voltage adjustment trim pin, + remote sense, remote on-off (positive or negative logic), input under-voltage, over-current and over-temperature protection.

All models have safety certification to the IEC/UL/CSA/EN 62368-1 standards, with CE marking to the Low Voltage and RoHS Directives.
