I was going to try to load the TI TPS54335 spice model into LTspice but it looks encrypted. Is TI encrypting its spice models now? http://www.ti.com/product/tps54335 Thanks
Are TI Pspice models encripted?

The posted PSpice model... while I've not yet tried it, looks like it only will do a Bode plot.

I wonder why the slope is negative. I like the specification... SYM PARAMETER TYPICAL CL Output Load Capacitance 1100 pF (max) So, that's a typical max? The data sheet is similarly funny in other places. Figs 9, 16, 17, and 18 are hoots. The LM35/45 series was a similar horror, with a nasty output stage, oscillation and latchup problems.

What's vague is the deviation with load. If I didn't know CMOS well, it would be difficult to figure out what they mean. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.
