Newly enhanced LTSpice model simplifies designing with GaN
Power system design engineers want to be fast, accurate and confident with their simulated designs prior to building hardware.
This is a product release announcement by GaN Systems. The issuer is solely responsible for its content.
Achieving these goals with GaN designs has become easier with GaN Systems’ new set of LTSpice models. Increasing efficiency and power density requires proper layout and understanding of the characteristics of these fast transistors. GaN Systems provides a full-featured set of LTSpice simulation files that are available now for download that allow for a variety of inputs and simulations options; select the product of interest and then select the LTSpice button. Additionally, LTSpice application notes GN007 and GN008 are available on the GaN Systems website.
The LTSpice model user guide helps engineers model systems at three levels, ranging from an initial overview of circuit performance to detailed analysis and fine tuning of the design:
- Level 1: Basic adjustment and analysis of switching speeds, optimized for quick simulation.
- Level 2: In additional to Level 1 features, includes thermal inputs and Cauer thermal RC network transient models for simulating the device junction temperature and self-heating effect.
- Level 3: In addition to Level 2 features, includes parasitic losses, provides the most accurate model with longest simulation times.
