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 1 7 P-TO263-7-2 P-TO220-7-3 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 • 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 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 ICs • Ideal for compact, highly-efficient, multi-phase voltage regulators on motherboards and VRMs P-TO220-7-230 |
