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

DIP-16

SOP-16

*Pb-free plating product number: TL494L
