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.

FEATURES

* Complete PWM power control circuitry

* Uncommitted outputs for 200mA sink or source current

* Output control selects single ended or push pull operation

* Internal circuitry prohibits double pulses over total range

* Easy synchronization
