Shutdown
During the shutdown sequence, BP6 is controlled by ENx/SSx. If both of ENx/SSx pins are pulled low, BP6 is
turned off regardless of the input voltage remaining higher than programmed UVLO threshold.
Switching Frequency and Master/Slave Synchronization
The switching frequency is set by the value of the resistor connected from the RT pin to AGND. The RT resistor
value is calculated in Equation 5.
where
RRT is the the resistor from RT pin to AGND, in Ω
fSW is the desired switching frequency, in Hz
(5)
The TPS40322 device can also synchronize to an external clock that is
±20% of the master clock frequency
which is two times the free running frequency. Each TPS40322 can be set by the PHSET pin as either master or
slave. The master produces a 50% duty cycle clock to the slave. The slave synchronizes to the external clock
with 50% duty cycle and selects the phase shift angle as shown in Table 1.
Figure 21 shows an example on synchronizing two TPS40322 devices to generate an evenly distributed shift to
reduce input ripple.
