TL598CDR

脉宽调制控制电路 PULSE-WIDTH-MODULATION CONTROL CIRCUITS

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.

Complete PWM Power-Control Function

Totem-Pole Outputs for 200-mA Sink or Source Current

Output Control Selects Parallel or Push-Pull Operation

Internal Circuitry Prohibits Double Pulse at Either Output

Variable Dead-Time Provides Control Over Total Range

Internal Regulator Provides a Stable 5-V Reference Supply, Trimmed to 1% Tolerance

On-Board Output Current-Limiting Protection

Undervoltage Lockout for Low-VCC Conditions

Separate Power and Signal Grounds
