TDA21472 — Overview
TDA21472 by Infineon Technologies is a component in the Power Management - Integrated Power Stage (DrMOS / Smart Power Stage) category, supplied by Shenzhen Jinteng Electronics Technology Co., Ltd. (JTDZ Tech) — an independent distributor serving OEMs, ODMs and EMS providers worldwide.
The TDA21472 is an Infineon OptiMOS integrated power stage (DrMOS) that co-packages a low-quiescent-current synchronous buck gate driver with a Schottky diode and high-side/low-side MOSFETs in a 5 x 6 x 1 mm PQFN (Infineon PG-IQFN-39) package. It delivers up to 70 A continuous output (80-A OCP), operates from a 4.25-V to 16-V input at switching frequencies up to 1.5 MHz, and provides 5-mV/A temperature-compensated on-chip current sensing. It targets multi-phase CPU/GPU/DDR voltage-regulator rails in servers, edge/AI systems and telecom infrastructure.
