Summary in PDF File


KEC m SEMICONDUCTOR KIA494AP AF TECHNICAL DATA BIPOLAR LINEAR INTEGRATED CIRCUIT Voltage Mode PWM Controller IC The KIA494AP AF incorporates on a single monolithic chip all the functions required in the construction of a pulse widthmodulation control circuit Designed primarily for power supply control this device offers the systems engineer the flexibility to tailor the power supply control circuitry to a specific application The KIA494AP AF contains two error amplifiers an on chip adjustable oscillator a dead tme control DTC comparator a pulse steering control flip flop a 5 V 5 precision requlator and output control circuits The error amplifiers exhibit a common mode voltage range from 0 3V to Vcc 2V The dead time control comparator has a fixed offset that provides approximately 5 dead time The on chip oscillator may be bypassed by terminating RT to the reference output and providing a sawtooth input to CT or it may drive the common circuits in synchronous multiplerail power supplies The uncommitted output transistors provide either commonemitter or emitter follower output capability The KIA494AP AF provides for push pull or single ended output operation which may be selected through the output control function The architecture of
