TDA21472 Integrated Circuit Chip OptiMOS™ Power Stage PG-IQFN-39 Smart Power Stages

TDA21472 Integrated Circuit Chip OptiMOS™ Power Stage PG-IQFN-39 Smart Power Stages​

Product Description Of TDA21472

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.

TDA21472 internal MOSFET current sense algorithm with temperature compensation achieves superior current sense accuracy versus best-in-class controller-based inductor DCR sense methods.

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.
