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
