GDTL494 V O LTA G E M O D E P WM C O N T R O L C I R C U I T Description The GDTL494 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.
