The Infineon Technologies TDA21462AUMA1 is a high-frequency, low-profile DC-DC converter power stage. It integrates a gate-driver IC, Schottky diode, and high-side/low-side MOSFETs in a single package optimized for PCB layout and heat transfer.
This device is suitable for voltage regulators for CPUs, GPUs, and DDR memory arrays, offering an input voltage range of 4.25 V to 16 V and an output voltage range from 0.25 V to 5.5 V. It features 70A output over-current protection and operates at switching frequencies up to 1.5 MHz, enabling high performance transient response.
The TDA21462AUMA1 includes on-chip MOSFET current sensing with temperature compensation, VCC/VDRV UVLO protection, phase fault detection, and thermal shutdown. It also supports a deep-sleep power saving mode for reduced consumption in PS3/PS4 states.
Packaged in a compact 5 mm x 6 mm PQFN, this lead-free and RoHS-compliant component is ideal for demanding server applications, as well as GPU and DDR memory designs.
