UTC TL494

LINEAR INTEGRATED CIRCUIT

VOLTAGE MODE PWM CONTROL

CIRCUIT

DESCRIPTION

The UTC TL494 incorporates all the functions required in

the construction of a pulse-width modulation switching circuit.

Designed primarily for switching power supply control or DC-

DC convectors, it offers the systems engineer the flexibility to

tailor control circuitry to its own application.

SOP-16

FEATURES

*Complete PWM power control circuitry

*Uncommitted outputs for 200 mA sink or source current

*Output control selects single ended or push pull operation

*Internal circuitry prohibits double pulses over total range

*Easy synchronization
