9.3.7 Adjustable Switching Frequency and Synchronization

There are multiple clocking mode options to enable use of both the programmable internal clock and an externally synchronized clock. This allows flexibility to synchronize devices to a system clock or to allow secondary TPS7H4011 devices to be synchronized to a primary TPS7H4011 device. All modes are listed in Table 9-3.

Table 9-3 Clock Modes
MODE INPUT CONFIGURATION FOR CLOCK CLOCK
SYNCM INPUT SYNC2 INPUT RT SYNC1 INPUT/OUTPUT SYNC2 OUTPUT
Internal clock: With output sync SYNCM = GND N/A Resistor from RT to GND Output fSW in phase Output fSW 90° out of phase
Internal clock: No output sync SYNCM = Float No output No output
External clock: Inverted sync, default fSW SYNCM = AVDD SYNC2 = GND Resistor from RT to GND Input fSW 180° out of phase N/A
External clock: Inverted sync, no default fSW Float Input fSW 180° out of phase N/A
External clock: Non-inverted sync, default fSW SYNC2 = AVDD Resistor from RT to GND Input fSW in phase N/A
External clock: Non-inverted sync, no default fSW Float Input fSW in phase N/A
