AIC3843
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 accuracy at the error amplifier input, high gain error amplifier, current sensing comparator, logic to insure latched operation, and a totem-pole output stage designed to source or sink high peak current.
