BCT3843S
BCT3843S
Current Mode Power Supply Control IC from BlueChips Technology
Features
The BCT3843SN control IC provides pin-for-pin replacement of the industry standard UC3843 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. The oscillator discharge current is trimmed to provide guaranteed duty cycle clamping rather than specified discharged current. The circuit is more completely specified to guarantee all parameters impacting power supply manufacturing tolerances.
In addition, the oscillator and flip-flop sections have been enhanced to provide additional performance. The RT/CT pin now doubles as a synchronization input that can be easily driven from open collector/open drain logic inputs. This sync input is a high impedance input and can easily be used for externally clocked systems.
The BCT3843S requires less than 0.5mA of start-up current over the full temperature range.
