The TL598 incorporates all the functions required in the construction of pulse-width-
modulated (PWM) controlled systems on a single chip. Designed primarily for power-supply
control, the TL598 provides the systems engineer with the flexibility to tailor the power-
supply control circuits to a specific application.
The TL598 contains two error amplifiers, an internal oscillator (externally adjustable), a
dead-time control (DTC) comparator, a pulse-steering flip-flop, a 5-V precision reference,
undervoltage lockout control, and output control circuits. Two totem-pole outputs provide
exceptional rise- and fall-time performance for power FET control. The outputs share a
