Description

The TDA21472 power stage contains a low quiescent-current synchronous buck gate-driver IC co-packaged

with Schottky diode, and high-side and low-side MOSFETs. The package is optimized for PCB layout, heat

transfer, driver/MOSFET control timing, and minimal switch node ringing when layout guidelines are followed.

The gate driver and MOSFET combination enables higher efficiency at the lower output voltages required by

cutting edge CPU, GPU and DDR memory designs.

The TDA21472 internal MOSFET current sense algorithm with temperature compensation achieves superior

current sense accuracy versus best-in-class controller-based inductor DCR sense methods. Protection includes

cycle-by-cycle over current protection with programmable threshold, VCC/VDRV UVLO protection, phase fault

detection, IC temperature reporting and thermal shutdown. The TDA21472 also features auto-replenishment of

the bootstrap capacitor to prevent over-discharging. The TDA21472 features a deep-sleep power saving mode,

which greatly reduces the power consumption when the multiphase system enters PS3/PS4 mode.

Operation at switching frequency as high as 1.5 MHz enables high performance transient response, allowing

reduction of output inductance and output capacitance while maintaining industry leading efficiency.

The TDA21472 is optimized for CPU core power delivery in server applications. The ability to meet the stringent

requirements of the server market also makes it ideally suited for powering GPU and DDR memory designs.
