Infineon Technologies TDA21301
TDA21301 is a multi-phase DC-DC buck converter controller integrated all control functions for the next generation GHz CPU voltage regulator. The multi-phase architecture is able to provide high output current with lower power dissipation on the switching devices and minimizing the input ripple current and output ripple voltage. The equivalent high operation frequency optimizes the voltage regulator design for better transient response and thermal performance.| Part No. | TDA21301 |
