Product Overview
LTC3727-1 is a high performance dual step-down switching regulator controller that drive 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. There is a precision 0.8V reference and a power good output indicator. A wide 4V to 30V (36V maximum) input supply range encompasses all battery chemistries. 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. It is widely used in applications such as telecom systems, automotive systems, battery-operated digital devices etc.
- ±1% output voltage accuracy, VIN range is 3.6V to 30V
- Power good output voltage monitor
- Dual N-channel MOSFET synchronous drive, latched short-circuit shutdown
- Adjustable soft-start current ramping, maximum duty factor is 99.4% typ at (t TA = 25°C, VIN = 15V)
- Foldback output current limiting, output overvoltage protection
- Selectable constant frequency or Burst Mode® operation
- Shutdown current is 20μA typical at (VRUN/SS1, 2 = 0V, TA = 25°C, VIN = 15V, VRUN/SS1, 2 = 5V)
- Operating temperature is -40°C to 85°C
- Package style is 28-lead plastic SSOP
