LT1028 works, but LT1028N, the one that brings out the comp pin, doesn't.

I have LTspice v4.19s, which I think is the latest. Searching the directory structure, I find neither an assembly (.ASY) or a model (.SUB, .LIB, or .MOD) for LT1028N. ...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.

Checked sync release, now up to 4.19u, no LT1028N. ...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.

It's in this library.... <http://www.gunthard-kraus.de/Spice_Model_CD/Vendor%20List/LinearTech/LTC37.lib> From the date of the library... is it an obsolete part? ...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.

where have you found LT1028N? I can't find it int the latest version, and when looking at the linear site it doesn't even exist -Lasse

Found it in this old library... <http://www.gunthard-kraus.de/Spice_Model_CD/Vendor%20List/LinearTech/LTC37.lib> It's not in the latest version of ASY symbols. ...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.

LT1028N symbol calls LTC.lib, but LT1028N isn't in there, only LT1028. It's not in any of the other .lib files, either, according to grep. Looks like they slipped up. -- "Design is the reverse of analysis" (R.D. Middlebrook)

Where did you find an LT1028N symbol? My v4.19u doesn't have it. Methinks it's been dropped. Haven't found a datasheet. ...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.

And searching the Linear website for LT1028N only returns LT1028. ...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.
