9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The following sections are partitioned to facilitate applying the TPS40140 in various modes and configurations.
The first sections describe functions that are used in all configurations. The following sections are specific to the
configuration (that is, single controller, multiple controllers, master and slave).
9.1.1 Synchronizing a Single Controller to an External Clock
The TPS40140 has the ability to synchronize a single controller to an external clock. The clock must be a pulse
stream at 6 or 8 times the master PWM frequency. See Figure 16.
Figure 16. Synchronizing a Single Controller to an External Clock
Synchronizing the single controller to an external clock is similar to synchronizing a clock slave to a clock master.
The single controller is put in clock slave mode by connecting the RT pin to BP5, disabling the internal clock
generator. If the external CLKIO signal is a clock stream without any missing pulses, the master synchronize to
an arbitrary pulse so there is no determinant phase synchronization. Without a missing pulse, the PWM
frequency is 1/8 of the external clock. If the external CLKIO signal has a missing pulse every 6 cycles or 8
cycles, the controller synchronizes based on the missing pulse which would be in the 6th or 8th position. With the
missing pulse, the phase synchronization of the master, to the missing pulse, can be controlled by the voltage on
the PHSEL pin. See the section on DIGITAL CLOCK SYNCHRONIZATION. Phase shifting would also be
desirable if more than one controller were to be synchronized to the same external clock. The high-level
threshold for the external clock is 3.2 V, and the low-level threshold is 0.5 V. The typical duty ratio is
approximately 0.5.
Figure 16 shows a time slice of the two external clock possibilities and the resulting PWM signal. EXT CLK-A is
the continuous clock with no missing pulse and the PWM-A signal could be frequency synchronized anywhere in
the clock stream. The PWM signal is at 1/8 of the EXT CLK-A frequency. EXT CLK-S is the external clock
stream with a missing pulse every 8 cycles. The phasing of the PWM-S is based on the voltage on the PHSEL
pin. For PHSEL grounded, the PWM-S signal is shifted 90 degrees from what would be the falling edge of the
missing pulse as shown in Figure 16.
