QW-R103-004,A
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 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
