Description

TDA21302 is a multi-phase DC-DC buck converter controller integrated all control functions for the next generation GHz CPU voltage regulator. TDA21302 automatically controls 2 to 4 interleaved buck switching power stage operation. 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.

TDA21302 utilizes the Sync FET Rds(on) in every channel as the current sense element. The differential current sense in every channel results precious channel current information to the controller for good droop adjustment, channel current balance, channel switching devices thermal balance and over current protection.
