LTC389x Synchronous DC/DC Controllers

Analog Devices Inc. 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.

Power Management ICs

Analog Devices Inc. Power Management ICs (PMICs) power innovation with precision and efficiency. With unmatched power densities, ultra-low noise technology, and superior reliability, Analog Devices’ PMIC portfolio supports complex power architectures in the most demanding applications, including industrial, automotive, and aerospace. Electronics engineers and designers are supported with power management evaluation boards and design tools, such as LTspice®, to ease development and optimize performance. From Silent Switcher® regulators and µModule® power solutions to advanced battery management, LDOs, and digital power control, ADI delivers high-efficiency, low-noise, and compact solutions that ensure reliability and scalability.

LTC3897 PolyPhase™ Synchronous Boost Controllers

Analog Devices LTC3897 PolyPhase™ Synchronous Boost Controllers with surge stopper provide input/output protection and an ideal diode controller. The device has a boost controller that drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor requirements. This allows the use of smaller inductors than the single-phase equivalent. Synchronous rectification reduces power loss and eases thermal requirements.
