The Infineon 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.

Thermal shutdown and fault flag
Cycle-by-cycle over current protection with programmable threshold and fault flag
MOSFET phase fault detection and flag
Auto-replenishment of bootstrap capacitor
Deep-sleep mode for power saving
Compatible with 3.3-V tri-state PWM input
Body-Braking load transient support
