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
