The LND494 incorporate on a single monolithic chip all the functions required in the construction of a pulse-width-modulation control circuit. Designed primarily for power supply control, these devices offer the systems engineer the flexibility to tailor the power supply control circuitry to his application. The LND494 contains an error amplifier, an on-chip adjustable oscillator, a dead time control comparator, pulse steering control flip-flop, a 5volt, 5% precision regulator, and output-control circuits. The error amplifier exhibits a commonmode voltage range from 0.3 volts to Vcc-2 volts. The dead-time control compactor has a fixed offset that provides approximately 5% dead time when externally altered. The on-chip oscillator may be by passed by terminating RT (pin 6) to the reference output and providing a sawtooth input to CT (pin 5), or it may be used to drive the common circuits in synchronous multiple-rail power supplies.
