Description
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 common source supply and common power ground terminals, which allow system
designers to eliminate errors caused by high current-induced voltage drops and common-mode noise.
The error amplifier has a common-mode voltage range of 0 V to VCC ? 2 V. The DTC comparator has a fixed
offset that prevents overlap of the outputs during push-pull operation. A synchronous multiple supply operation
can be achieved by connecting RT to the reference output and providing a sawtooth input to CT.
