TPS54350-EP
SGLS308 – OCTOBER 2005
The SYNC pin is configurable as an input or as an output, per the description in the previous section. When
operating as an input, the SYNC pin is a falling-edge triggered signal (see Figure 3, Figure 4, and Figure 19).
When operating as an output, the signal's falling edge is approximately 180
° out of phase with the rising edge of
the PH pins. Thus, two TPS54350 devices operating in a system can share an input capacitor and draw ripple
current at twice the frequency of a single unit.
When operating the two TPS54350 devices 180
° out of phase, the total RMS input current is reduced. Thus
reducing the amount of input capacitance needed and increasing efficiency.
When synchronizing a TPS54350 to an external signal, the timing resistor on the RT pin must be set so that the
oscillator is programmed to run at 90% to 110% of the synchronization frequency.
NOTE:
Do not use synchronization input for designs with output voltages >10 V.
