Product Overview
The LTC3727EG#PBF is a high-performance dual step-down Switching Regulator Controller drives all N-channel synchronous power MOSFET stages. The 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. There is a precision 0.8V reference and a power good output indicator. A wide 4 to 30V (36V maximum) input supply range encompasses all battery chemistries. A RUN/SS pin for each controller provides soft-start and on the LTC3727GN, optional timed, short-circuit shutdown. Current foldback limits MOSFET heat dissipation during short-circuit conditions when overcurrent latch-off is disabled. Output overvoltage protection circuitry latches on the bottom MOSFET until VOUT returns to normal.
- Out-of-phase controllers reduce required input capacitance and power supply induced noise

- ±1% Output voltage accuracy
- Power good output voltage monitor
- Dual N-channel MOSFET synchronous drive
- Adjustable soft-start current ramping
- Foldback output current limiting
