Application Information :
TDA21301 is a multi-phase DC/DC controller that precisely regulates CPU core voltage and balances
the current of different power channels. The converter consisting of TDA21301 and its companion
CoreControl TM drivers, provides high quality CPU core power and all the protection functions to meet the
requirement of the latest CPUs.
Voltage Control
The TDA21301 senses the CPU V CORE by SGND pin via a resistor connecting to Vss_sense pin of CPU
and by FB pin via a resistor connecting to Vcc-sense of CPU to achieve the on-die voltage sense and to
minimize the voltage drop on the PCB traces at heavy load condition. FB pin is also the input of the
PGOOD & OVP sense. The internal highly accurate VID DAC provides the reference voltage for
VRD10.X compliance. Control loop consists of an error amplifier, a pulse width modulator, external
driver ICs and power elements. As a conventional voltage mode controller, the output voltage is locked
at the V REF of the error amplifier which is the output voltage of VID DAC plus setting offset and droop
and the error signal is used as the control signal, Vc of the pulse width modulator. The PWM signals at
different channels are generated by comparison of EA output and split-phase saw-tooth wave with
additional current signal to achieve the balance current at each channel. Power stage transforms V IN to
output by PWM signal on-time ratio.
