Tools & Simulations

LTspice 2

Models for the following parts are available in LTspice:

LT8580

LTpowerCAD 1

LT8580 Project - Boost Supply (3-10V to 12V @ 120mA)

LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.

LTpowerCAD^® is a power supply design program which selects power stage components, provides detailed power efficiency, shows quick loop Bode plot stability and load transient analysis, and can export to LTspice for simulation.

Evaluation Kits

LT8580 Demo Board | Boost, 3V ≤ VIN ≤ 10V, VOUT = 12V @ 120mA

Product Details

Demonstration circuits 2186A-A and 2186A-B feature the LT8580EDD in boost/inverting configurations. The demo circuits demonstrate small size and low component count. The DC2186A-A boost demo board is designed to convert a 3V to 10V source to 12V at 120mA. The DC2186A-B two inductor inverting (Cuk) demo board converts a 5V to 12V source to –12V at 150mA. Please refer to figures in the manual for maximum load current at different input voltage levels.
