Product Overview

The LTC3728EG#PBF is a dual high performance step-down Switching Regulator Controller that drives all N-channel synchronous power MOSFET stages. A constant-frequency current mode architecture allows phase-lockable frequency of up to 550kHz. Power loss and noise due to the ESR of the input capacitors are minimized by operating the two controller output stages out of phase. OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The precision 0.8V reference and power good output indicator are compatible with future microprocessor generations and a wide 3.5 to 30V (36V maximum) input supply range encompasses all battery chemistries. A RUN/SS pin for each controller provides both soft-start and optional timed, short-circuit shutdown. Current foldback limits MOSFET dissipation during short-circuit conditions when overcurrent latch-OFF is disabled.
  • Power good output voltage indicator
  • Dual N-channel MOSFET synchronous drive
  • Adjustable soft-start current ramping
  • Foldback output current limiting
  • Latched short-circuit shutdown with defeat option
  • Output overvoltage protection
  • Remote output voltage sense
  • ±1% Output voltage accuracy
  • 99% Duty cycle very low dropout operation
