TDA21570 Infineon Technologies 70A Integrated Power Stage IQFN-39 | JTDZ Tech
TDA21570 — Overview
TDA21570 by Infineon Technologies is a component in the Power Management - Integrated Power Stage (OptiMOS 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 TDA21570 is an Infineon OptiMOS 6 integrated 70-A power stage that combines a low-quiescent-current synchronous buck gate driver, an active diode and control/synchronous MOSFETs in a 5 x 6 x 0.9 mm PQFN (Infineon PG-IQFN-39) package. It operates from a 4.25-V to 16-V input at switching frequencies up to 1.5 MHz and provides 5-uA/A on-chip current sensing with 3% current/temperature telemetry and 8-mV/C analog temperature output. It is intended for multiphase CPU/GPU/DDR voltage regulators in servers, edge computing and telecom infrastructure; note that it is a distinct device from the TDA22570.
