TPS40120
SLUS616B–JULY 2004–REVISED AUGUST 2004
Typical application circuit for TPS40120 and TPS40090 combination is presented on the front page. Normally,
the TPS40120 accepts power from the BP5 pin of the TPS40090 multiphase controller which simplifies its
enable/disable control. The upper resistor of the programmable divider (pin 8) is connected to the output of the
differential amplifier DIFFO. The center tap of the divider (pin 9) is connected to the joint point of the FB pin of
the multi-phase controller and error amplifier compensation network. TPS40120 has two logic NCPUx outputs
that can be used to control output and the gate drivers in a multi-phase power supply when no-CPU code is
asserted. The NCPU1 output is an open drain that can be useful by discharging the soft-start capacitor and
bringing the output voltage down. The push-pull NCPU2 output can be used to control gate drivers to provide
high impedance of the power supply output in off state.
The application circuit for a four-phase 105-A CPU VRM10.x compliant power supply is shown in Figure 3.

For detailed information on TPS40090 multiphase controller and design example request the TPS4009x
datasheet (SLUS578) and the user's guide (SLUU026).
