General Description
The Integrated Switch TDA21201 incorporates an intelligent MOSFET driver and two
Power MOSFETs in a single package to form a fully integrated and optimized power
stage of a DC/DC synchronous buck converter including the bootstrap components
for the high-side MOSFET.
The Power MOSFETs are optimized for lowest static and dynamic losses for a 12 V
to sub-3.5 V conversion and can handle up to 30 A output current. The TDA21201 is
manufactured in Infineon′s state-of-the-art multi-chip assembly using a low-Rth 7-Pin

Features
Replaces with one part only the semiconductors of a DC/DC
power stage for a 12 V
à
1 ... 3.3 V conversion:
FET driver + High side FET + Low side FET
Raises the efficiency by reducing static and dynamic losses
beyond 85 % due to optimized MOSFETs and Driver
Reduces overall part count and board space consumption
