TL598CDR规格书详情
TL598CDR属于集成电路(IC)的PMIC-稳压器-DCDC开关式控制器。由美国德州仪器公司制造生产的TL598CDRDC-DC 开关控制器PMIC(电源管理集成电路)DC 到 DC 开关式控制器是用于高效率电路的稳压 IC,其配置为生成高于(突升或步升)或低于(突降或步降)输入电源的输出电源电压。其他拓扑结构可能包括:降压-升压、反激、正激、Cuk、SEPIC、全桥、半桥和推挽式。这些器件不同于需要最小电压并“烧尽”多余电压的线性稳压器。

description/ordering information
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.
The TL598 device provides an output control function to select either push-pull or parallel operation. Circuit
architecture prevents either output from being pulsed twice during push-pull operation. The output frequency
for push-pull applications is one-half the oscillator frequency fO
