Infineon Technologies AG DC-DC Converters, Integrated Smart Power Stages TDA21472

Description
TDA21472 OptiMOS™ Powerstage 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.
