The Infineon Technologies TDA21470 is a high-efficiency integrated power stage, part of a new generation of devices optimized for processor power delivery in server, telecom, and datacom applications. It combines advanced low-voltage MOSFET technology with Infineon's latest driver design, housed in a compact 5x6 mm PQFN package with a 0.45 mm pitch.
This device offers a wide input voltage range of 4.25 V to 16 V and supports output voltages from 0.25 V to 5.5 V, with an impressive output current capability of up to 70 A. It features fast switching technology for improved performance at higher frequencies and achieves a peak efficiency greater than 95%. The internal MOSFET Rds(on) current sensing provides accurate current reporting.
Key electrical characteristics include a typical supply current of 2.5 mA and a low quiescent current of less than 200 µA in disable mode (PS4). The TDA21470 supports operation up to 1.5 MHz and is optimized for 5 V drive.
Designed for surface mounting, the TDA21470's small footprint and high integration make it suitable for space-constrained designs requiring efficient power management for CPU cores, GPUs, and DDR memory.
