Integrated Switch

MOSFET Driver and MOSFETs
• Replaces with one part only the semiconductors of a DC/DC power stage for a 12 V à 1 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 overtemperature 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 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
