The LTC3882IUJ#TRPBF is a switching voltage regulator controller that is part of a family of Polyphase DC/DC controllers available from a number of big names, including Linear Technology. This type of controller offers a wide range of features and capabilities including multiple output configurations, sequenced power up/down inputs, high efficiency over a wide load range, flexible interoperability, and a wide operating temperature range. This makes it ideal for use in a wide range of applications, such as embedded computing, automotive, industrial control, instrumentation, and communications and networking systems.

The LTC3882IUJ#TRPBF is designed to work with an external power MOSFET switch. It uses an internal voltage-mode control loop to adjust the ratio of periods to the off and on times of the MOSFET switch. This ratio of duty cycles is used to maintain the desired output voltage from the switched converter. The duty cycle is adjustable, so the device can be used to regulate both the peak and average output voltage of a given converter circuit.

The LTC3882IUJ#TRPBF can operate in both forced PWM mode and voltage-mode control modes. In each mode, its operation can be adjusted and optimized as needed. In forced PWM mode, the duty cycle of the MOSFET switch is maintained at a fixed level, allowing for very fast transient response. In voltage-mode control mode, the device takes feedback from a voltage sensing circuit and adjusts the duty cycle to maintain a fixed output voltage.

The output voltage of the LTC3882IUJ#TRPBF can be adjusted from 0.6V to 44V. Additionally, it can handle maximum input voltages of up to 40V, offering further protection for systems that are subject to various forms of power supply transients. The voltage-mode control also allows for improved efficiency when working with higher input voltages. The LTC3882IUJ#TRPBF also offers overcurrent and overvoltage protection, making it suitable for use in a range of demanding applications.

The LTC3882IUJ#TRPBF uses a Programmable Multiphase (PMP) architecture to reduce component count, cost, and board space. It includes integrated current-sense amplifiers, MOSFET drivers, voltage reference, and oscillator. It also offers integrated thermal protection, enabling it to be used in environments where temperature management is key. Additionally, it incorporates a digital remapper that allows multiple phase configurations of up to 8 phases.

The LTC3882IUJ#TRPBF is a highly efficient, adjustable voltage regulator controller that can be used in a range of applications, most notably in embedded computing, automotive, industrial control, instrumentation, and communications and networking systems. It is designed to work with an external power MOSFET switch and uses a voltage-mode control loop to adjust the duty cycle of the MOSFET switch, offering improved transient response times as well as improved efficiency when working with higher input voltages. The device offers multiple output voltage ranges, overcurrent and overvoltage protection, integrated current-sense amplifiers, MOSFET drivers, voltage reference, and oscillator, and integrated thermal protection, making it highly suitable for a range of demanding applications.
