TDA38640 Description
The TDA38640 is an easy-to-use, fully integrated and highly efficient dc-dc regulator with Intel SVID and I2C/PMBUs interfaces. The controller utilizes Infineon’s fast COT engine which simplifies the design efforts, and achieves faster transient response. The onboard PWM controller and OptiMOS™ FETs with integrated bootstrap diode make TDA38640 a small footprint solution, providing high-efficiency power delivery for...
