The LTC3890 is a high performance dual step-down switching regulator DC/DC controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows a phase-lockable frequency of up to 850kHz. Power loss and noise due to the ESR of the input capacitor are minimized by operating the two controller output stages out-of-phase. The 50μA no-load quiescent current extends operating run time in battery-powered systems. OPTI-LOOP® compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The LTC3890 features a precision 0.8V reference and power good output indicators. A wide 4V to 60V input supply range encompasses a wide range of intermediate bus voltages and battery chemistries. Independent TRACK/SS pins for each controller ramp the output voltages during start-up. Current foldback limits MOSFET heat dissipation during short-circuit conditions. The PLLIN/MODE pin selects among Burst Mode operation, pulse-skipping mode, or continuous conduction mode at light loads. For a leaded package version (28-lead Narrow SSOP), see the LTC3890-1 data sheet.

LTC389x Synchronous DC/DC Controllers
Linear Technology/Analog Devices LTC389x Synchronous Controllers are high-performance step-down switching regulator DC/DC controllers. The LTC389x controllers, with the exception of the LTC3894 series, drive all N-channel synchronous power MOSFET stages. The MOSFET stage can operate from input voltages up to 150V. The high-voltage LTC3894 Controllers drive a P-channel power MOSFET switch. LTC389x's constant-frequency, current-mode architecture achieves up to an 850kHz phase-lockable frequency. Designers can program the gate drive voltage from 5V to 10V. This programming enables the use of standard-level or logic FETs for maximum efficiency. Using external resistors, designers can also program the output voltage from 0.8V to 60V. Pin-programming allows for a fixed 5V or 3.3V output voltage.
