TS494
Voltage Mode PWM Controller
DIP-16
Supply Voltage Range 7 V to 40V
Output Driving Current 200mA
Oscillator Frequency up to 200KHz
General Description
The TS494 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, these devices offer the systems
engineer the flexibility to tailor the power supply control circuitry to his application.
The TS494 contains an error amplifier, an on-chip adjustable oscillator, a deed-time control comparator, pulse-steering
control flip-flop, a 5-volt, 5% precision regulator, and output-control circuits. The error amplifier exhibits a
common-mode voltage from –0.3V to Vcc –2V. The dead-time control comparator has a fixed offset that provides
approximately 5% dead time when externally altered. The on-chip oscillatory be bypassed by terminating R
T
(pin 6) to
the reference output and providing a sawtooth input to C
T
(pin 5), or it may be used to drive the common circuits in
synchronous multiple-rail power supplies. The uncommitted output transistor provide either common-emitter or
emitter-follower output capability. Each device provides for push-pull or single-ended output operation, which may be
selected through the output-control function. The architecture of these devices prohibits the possibility of either output
being pulsed twice during push-pull operation.
The TS494 is offered in SOP-16 and DIP-16 package.
