LINEAR Design Note 501 Manual
The LT3791 is a 4-switch synchronous buck-boost DC/DC converter that regulates both constant-current and constant-voltage at up to 98.5% efficiency with a single inductor. It can deliver hundreds of watts and features a 60V input and output rating, making it ideal for driving high power LED strings and charging high voltage batteries when both step-up and step-down conversion is needed. It can also be used as a constant-voltage buck-boost regulator with current limiting and monitoring for both input and output.
LINEAR Design Note 1024 Manual
This document introduces the LTC3890 and LTC3891 step-down DC/DC controllers. These controllers can accept inputs from 4V to 60V and support single and dual battery automotive environments. They can also output 12V 25A. If no galvanic isolation is required between the input and output voltages, the LTC3890 and LTC3891 can replace expensive and bulky transformer-based converters. Compared to transformer-based solutions, the LTC3890 and LTC3891 step-down converters increase efficiency, reduce power loss in the supply lines, simplify layout and significantly reduce the bill of materials.
LINEAR Design Note 502 Manual
This design note introduces matched resistor networks for precision amplifier applications and describes how to achieve high-precision matched resistor networks using the LT5400 amplifier.
LINEAR Design Note 1028 Manual
The LTC3838 is a dual output, dual phase buck controller that employs a controlled constant on-time, valley current mode architecture to provide fast load step response, high switching frequency and low duty cycle capability. It accepts a wide input range, 4.5V to 38V, and can produce 0.6V to 5.5V outputs.
LINEAR Design Note 1027 Manual
This article discusses how to optimize performance by minimizing IM2 nonlinearity and DC offset that reduce the dynamic range of zero-IF receivers, thus offering a viable alternative to an otherwise challenging design.
LINEAR Dual DC/DC Controller for DDR Power with Differential VDDQ Sensing ±50mA VTT Reference Design Note 503
This document introduces the LTC3876, a complete DDR power solution that is compatible with DDR1, DDR2, DDR3 and DDR4 lower voltage standards. The IC includes VDDQ and VTT DC/DC controllers and a precision linear VTT reference.
LINEAR 42V 2.5A Synchronous Step-Down Regulator with 2.5 A Quiescent Current Design Note 504
The LT8610 and LT8611 are 42V, 2.5A synchronous step-down regulators that meet the stringent high input voltage and low output voltage requirements of automotive, industrial and communications applications. By replacing an external Schottky diode with an internal synchronous power switch, the solution size is minimized and efficiency is increased while reducing power dissipation. These regulators are designed to be compact and allow inductor size to be selected based on the output load requirements of the application, providing short-circuit robustness.

LINEAR 2PB_2882e Isolated RS232 + 1W Power
The LTM®2882 is an isolated RS232 transceiver that guards against large ground-to-ground differentials. The LTM2882’s internal inductive isolation barrier breaks ground loops by isolating the logic level interface and line transceiver. An onboard DC/DC converter provides power to the transceiver, with an isolated 5V supply output for powering additional system circuitry. With 2500VRMS galvanic isolation, onboard secondary power and two RS232 drivers and receivers, the LTM2882 requires no external components and provides a small, complete µModule solution for isolated serial data communications.
