20-A models join buck converter lineup

TDK-Lambda expands its i7A series of non-isolated step-down DC/DC converters with seven 500-W models that provide 20 A of output current. The converters occupy a standard 1/16^th brick footprint and use a standardized pin configuration.

With an input voltage range of 28 V to 60 V, the new converters offer a trimmable output of 3.3 V to 32 V and achieve up to 96% efficiency. This high efficiency reduces internal losses and allows operation in ambient temperatures ranging from -40°C to +125°C. Additionally, an adjustable current limit option helps manage stress on the converter and load during overcurrent conditions, enabling precise adjustment based on system needs.

The 20-A i7A models are available in three 34×36.8-mm mechanical configurations: low-profile open frame, integrated baseplate for conduction cooling, and integrated heatsink for convection or forced air cooling.

Samples and price quotes for the i7A series step-down converters can be requested on the product page linked below.
