Preliminary Data Sheet
TDA21201
Integrated Switch
(MOSFET Driver and MOSFETs)
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 _P-TO220-7-3
• Simplifies and shortens the circuit design and the layout
• Eliminates the need for external bootstrap components
• Provides simplest overall output current scalability
• Protects the Driver and the MOSFETs against over-
temperature and shoot-through problems Vcc à Gnd
• Achieves the lowest thermal resistance Rthjc and Rthja
• Uses the well-known, easy-to-assemble and robust
P-TO220-7-230
standard TO-220 and TO-263 (D²Pak) package
• Requires no separate supply voltage to operate except 12 V
• Three state input to enable a shut down mode to turn off
both MOSFETs
• Compatible with standard 2-, 3-, 4-, 6-phase PWM controller

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
