AS3843 - Current Mode Controller
The AS3842 family of control ICs provide pin-for-pin replacement of the industry standard UC3842 series of devices.
The devices are redesigned to provide significantly improved tolerances in power supply manufacturing.
The 2.5 V reference has been trimmed to 1.0% tolerance.
