• LT spice LTspice is a high performance SPICE simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators. Our enhancements to SPICE have made simulating switching regulators extremely fast compared to normal SPICE simulators, allowing the user to view waveforms for most switching regulators in just a few minutes. Included in this download are LTspice, Macro Models for majority of Linear Technology's switching regulators, over 200 op amp models, as well as resistors, transistors and MOSFET models.
LTspice for Windows 7, 8, and 10 was updated on and includes all recent models. Support for Windows XP version has ended and will no longer be updated.
• • • • • • • • • LTpowerCAD II LTpowerCAD II The LTpowerCAD II design tool is a complete power supply design tool program that can significantly ease the tasks of power supply design with Linear Technology µModule regulators and many other products, mostly monolithic buck step-down regulators. Unlike conventional simulation tools, this LTpowerCAD tool guides users throughout the whole supply design process: it searches suitable LTC parts according to user’s supply specifications; then it guides the user to select and optimize circuit component values with suggestions and warnings. The tool shows real-time results of feedback loop bode plot, as well as the power stage performance. The design can be exported to LTspice simulation circuit for users to further verify their designs. The tool also provides PCB layout examples. Currently, this design tool works on Microsoft Windows based PC with Excel 2000, 2003, 2007, 2010 and 2013.
With internet connection, the user can make real time update of the program and its component library. Contact LTpowerCAD@linear.com for questions or support. LTpowerPlanner Included in the LTpowerCAD toolbox, there is also an LTpowerPlanner system architecture tool for system-level power management design and optimization. • • • • LTpowerPlay LTpowerPlay LTpowerPlay is a powerful, Windows-based development environment supporting Linear Technology's (PSM) products, including PMBus Power System Managers (such as, ) and DC/DC Power Converters with PSM (,, ). The software supports a variety of different tasks. You can use LTpowerPlay to evaluate Linear Technology ICs by connecting to a demo board system.
LTpowerPlay can also be used in an offline mode (with no hardware present) in order to build a multi-chip configuration file that can be saved and reloaded at a later time. LTpowerPlay provides unprecedented diagnostic and debug features.
It becomes a valuable diagnostic tool during board bring-up to program or tweak the power management scheme in a system or to diagnose power issues when bringing up rails. LTpowerPlay utilizes the USB-to-I2C/SMBus/PMBus controller to communicate with one of many potential targets, including the evaluation board, or a customer target system. The software also provides an automatic update feature to keep the software current with the latest set of device drivers and documentation.

The code is designed to be highly portable to other microcontroller platforms, and is written in C using as few processor specific functions as possible. The code libraries can be downloaded by clicking the Downloads tab above and used as-is in your project or individual code snippets may be viewed in the Code section of a supported part. The Linduino One board (Demonstration Circuit DC2026) allows you to test out the code directly, using the standard demo board for the particular IC.
The Linduino One board is compatible with the Arduino Uno, using the Atmel ATMEGA328 processor. This board features a 14-pin “QuikEval” connector that can be plugged into nearly 100 daughter boards for various Linear Technology parts, including Analog to Digital converters, Digital to Analog Converters, high-voltage power monitors, temperature measurement devices, RF synthesizers, battery stack monitors, and more. An LTM2884 USB Isolator breaks the ground connection to the PC, allowing projects to operate at a different ground potential than the computer that is controlling it. • For downloads, frequently asked questions and lists of supported products, please visit LinearLab Tools LinearLab Tools LinearLabTools is a collection of Matlab and Python programs that provide direct access to Linear Technology’s data converter evaluation boards. An evaluation board for a data converter will typically plug into an accompanying controller board, which is then connected to a host computer running a Linear supplied GUI program such as PScope for Analog-to-Digital converters or LTDACgen for Digital-to-Analog converters. The GUI allows basic performance measurements to be made, but it is not designed to run arbitrary sequences of tests or communicate with other hardware, as is often required by customers when evaluating a part for their own application. LinearLabTools allows customers to control Linear’s data converter demo boards as they would any other piece of test equipment, using their own software.
