DESCRIPTION
The AIC3843 control IC provides the features that are necessary to implement off-line or DC/DC Converter fixed-frequency current-mode schemes with a minimum number of external components.
This integrated circuits features an under-
voltage lockout (UVLO) with approximately 300µA start-up current, a precision reference trimmed for a...
