TDA21301 Description

TDA21301 developed by Infineon Technologies is a member of multi-phase PWM controllers for CPU core power supply. It uses the digital output of the microprocessor to control the analog circuit, which is a method of digitally encoding the analog signal level. Controlling analog circuits digitally can greatly reduce the cost and power consumption of the system. It is capable of achieving active droop compensation for fast load response and smooth VCORE voltage transition during the dynamic VIDs.
