TECHNICAL DATA
PWM Control Circuit
KK494
The KKK494 incorporates 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, the KK494 contains an on-
chip 5-volt regulator, two error amplifiers, adjustable oscillator, dead-
time control comparator, pulse-steering flip-flop, and output-control
circuitry. The uncommitted output transistors provide either common-
emitter or emitter-follower output capability. Push-pull or single-ended
output operation may be selected through the output-control function. The
architecture of the KK494 prohibits the possibility of either output being
pulsed twice during push-pull operation.
• Complete PWM Power Control Circuitry
• Uncommitted Outputs for 200 mA Sink or Source
• Output Control Selects Single-Ended or Push-Pull Operation
• Internal Circuitry Prohibits Double Pulse at Either Output
• Internal Regulator Provides a Stable 5 V Reference Supply
• Variable Dead-Time Provides Control Over Total Range
