TDA21472 Description

Short technical summary and product information.

The TDA21472 from Infineon is an integrated smart power stage solution for DC-DC converters, optimized for CPU core power delivery in server applications, but also suitable for GPU and DDR memory designs. This device integrates a gate-driver IC, Schottky diode, and high-side/low-side MOSFETs in a compact 5 mm x 6 mm PQFN package.

Key electrical specifications include an input voltage range of 4.25 V to 16 V and an output voltage range from 0.25 V up to 5.5 V. It operates at switching frequencies as high as 1.5 MHz, enabling high performance transient response and reduced output inductance and capacitance. The TDA21472 features on-chip MOSFET current sensing with temperature compensation, providing 5-mV/A accuracy. Protection features include cycle-by-cycle over-current protection with a programmable threshold, VCC/VDRV UVLO, phase fault detection, IC temperature reporting, and thermal shutdown. It also includes auto-replenishment of the bootstrap capacitor and a deep-sleep mode for power saving.

The package is designed for optimized PCB layout, heat transfer, and minimal switch node ringing. The TDA21472 is lead-free and RoHS compliant.
