Product Overview
LTC3892-1 is a high performance dual step-down DC/DC switching regulator controller that drives all N-channel synchronous power MOSFET stages. Power loss and noise are minimized by operating the two controller output stages out-of-phase. The gate drive voltage can be programmed from 5V to 10V to allow the use of logic or standard-level FETs and to maximize efficiency. Internal switches in the top gate drivers eliminate the need for external bootstrap diodes. A wide 4.5V to 60V input supply range encompasses a wide range of intermediate bus voltages and battery chemistries. Output voltages up to 99% of VIN can be regulated. OPTILOOP® compensation allows transient response and loop stability to be optimized over a wide range of output capacitance and ESR values. The 29μA no-load quiescent current extends operating run time in battery powered systems. Applications include automotive and industrial power systems, distributed DC power systems and high voltage battery operated systems.
- Wide VIN range from 4.5V to 60V (65V abs maximum)
- Wide output voltage range from 0.8V ≤ VOUT ≤ 99% • VIN
- Adjustable gate drive level 5V to 10V (OPTI-DRIVE)
- No external bootstrap diodes required, low operating IQ: 29μA (one channel on)
- Selectable gate drive UVLO thresholds
- Out-of-phase operation reduces required input capacitance and power supply induced noise
- Phase-lockable frequency from 75KHz to 850KHz
- Selectable continuous, pulse skipping or low ripple burst mode operation at light loads
- Low shutdown IQ: 3.6μA
- 28-lead plastic TSSOP package, -40°C to 125°C temperature range
