The TDA21490 from Infineon Technologies is a high-frequency, low-profile DC-DC converter power stage. It integrates a gate-driver IC with high-side and low-side MOSFETs in a compact PQFN package optimized for PCB layout and heat transfer.
This power stage operates with an input voltage range of 4.25 V to 16 V and a VCC/VDRV supply range of 4.25 V to 5.5 V. It offers an output DC current capability of 70 A and a peak current capability of 90 A. The device supports switching frequencies up to 1.5 MHz, enabling high-performance transient response and allowing for reduced output inductance and capacitance.
Key features include on-chip MOSFET current sensing with temperature compensation, providing 5-mV/A accuracy. Protection features include cycle-by-cycle over-current protection, VCC/VDRV UVLO, bootstrap capacitor under-voltage protection, phase fault detection, and thermal shutdown. The TDA21490 also includes a deep-sleep mode for power saving.
Designed for CPU core power delivery in server applications, the TDA21490 is also well-suited for powering GPU and DDR memory designs. Its small 5 mm x 6 mm x 1 mm PQFN package is suitable for surface mount applications.
