UC1823: LTSpice Model Download

Emily,

No models are available for UC1823 but I see an unencrypted SPICE model and TINA model in the UC1825B product folder. Otherwise, you can parametrically search TI push-pull PWM controllers and then visit the corresponding product folders to see what models might be available.

Also, you can get better support for TI models running on TI simulation tools such as PSPICE for TI. LT Spice is not supported by TI.
