Description
KA3842AC/KA3842AE SMPS Controller March 2006 KA3842AC/KA3842AE SMPS Controller .
The KA3842AC/KA3842AE are fixed PWM controllers for Off Line and DC to DC converter applications.
Features
* Low start current 0.2mA (Typ. )
* Operating range up to 500kHz
* Cycle by cycle current limiting
* Under Voltage Lock Out (UVLO) with hysteresis
* Short shutdown delay time: Typ.100ns
* High current totem-pole output
* Output swing limiting: 2
Applications
* The internal circuits include UVLO, low start up current, temperature compensated reference, high gain error amplifier, current sensing comparator, and high current totem pole output for driving a POWER MOSFET. Also KA3842AC/KA3842AE provides low start up current below 0.3mA and short shutdown dela
