LT3992EUH#PBF is a monolithic, low quiescent current, synchronous buck switch regulator, targeting industrial and communications applications such as voltage regulators for motor and motor control. It features a wide input voltage range from 2.25 V to 60 V, operating in either Step-down, Step-up and Buck-Boost modes. The regulator is in compliance with the Digital LoadlineTM technology, ensuring proper peak output voltage and validating proper voltage loading. It provides multiple protection features including cycle-by-cycle current limiting and thermal shutdown.

The internal switch can support up to 5 V output voltage in Step-up, Step-down and Buck-Boost modes. It has higher continuous output current capability, up to 1.2 A and has unique output disconnect and “Power Good” features which detect output voltage over and under-voltages.

The device is ideal for supplies with high peak-to-peak voltage transients, such as automotive and battery supplies. In addition, the LT3992EUH#PBF can operate from an unregulated or step-down buck converter, providing an easy way to establish a superior voltage regulation for motor drive applications.

The LT3992EUH#PBF uses an advanced synchronous current-mode control structure to ensure stable operation even with sudden load changes. It provides low output voltage transient in order to meet most modern voltage regulator requirements. The LT3992EUH#PBF also uses a fractional-N architecture to reduce output ripple voltage.

The device is easy to use, and provides a single resistor divider and single capacitor loop compensation, making it suitable for regulating and controlling the output voltage precisely. In order to reduce input-output voltage differential, it has an integrated differential amplifier which reduces output voltage error even with large input-output voltage differences. It also has a “power good” signal to show the state of the system.

The LT3992EUH#PBF is available in a large variety of form factors and package types, making it ideal for a variety of applications, such as motor, LED, power supply and system power systems. Furthermore, it is also compatible with virtually all of today’s popular processors and controller ICs.

It features a wide input voltage range from 2.25 V to 60 V, making it suitable for high current applications, while the wide operating temperature range (from -65 °C to 150 °C) makes it suitable for high temperature applications. The device is designed to reduce power consumption and provide low power dissipation.

The LT3992EUH#PBF offers an internal soft-start which allows the user to select the ramp-up of the output voltage at power-up and/or at other occasions. It also has various protection features such as cycle-by-cycle current limiting, thermal shutdown and power good signal.

Overall, the LT3992EUH#PBF is an ideal product for those looking for high performance, cost effective and reliable DC-DC switching regulators. It is ideally suited for use in applications such as motor and motor control, power supply and system power systems, LED, and other general industrial and communications applications.
