This Topologies circuit may be configured to provide control in either • Practical Operation at Switching Frequencies voltage or current mode operation, with a separate to 1 MHz overcurrent shutdown for fast fault protection • Four 2-A Totem Pole Outputs A programmable time delay is provided to insert a • 10 MHz Error Amplifier dead-time at the turn-on of each output stage. This delay, providing time to allow the resonant switching • Undervoltage Lockout action, is independently controllable for each output • Low Startup Current – 150 µA pair (A-B, C-D). • Outputs Active Low During UVLO With the oscillator capable of operation at frequencies • Soft-Start Control in excess of 2 MHz, overall switching frequencies to • Latched Overcurrent Comparator With Full 1 MHz are practical. In addition to the standard free Cycle Restart running mode, with the CLOCKSYNC pin, the user may configure these devices to accept an external • Trimmed Reference clock synchronization signal, or may lock together up to 5 units with the operational frequency determined APPLICATIONS by the fastest device • Power FPGAs spacer BLOCK DIAGRAM 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
