Product Overview

The LTC1628IG-PG#PBF is a high-performance dual step-down Switching Regulator Controller drive all N-channel synchronous power MOSFET stages. The constant frequency current-mode architecture allows adjustment of the frequency up to 300kHz. 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.
  • Out-of-phase controllers reduce required input capacitance and power supply induced noise
  • OPTI-LOOP® Compensation minimizes COUT
  • ±1% Output voltage accuracy
  • 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
  • 20µA Low shutdown
  • Selectable constant frequency or burst mode operation
  • Power good output voltage monitor
