Product Summary
The TL598 pulse-width-modulation control circuit. It 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.
Parametrics
TL598CN absolute maximum ratings: (1)Supply voltage, VCC(see Note 1) 41V; (2)Amplifier input voltage, VI: VCC + 0.3 V; (3)Collector voltage :41 V; (4)Output current (each output), sink or source, IO:250 mA; (5)Package thermal impedance, θJA(see Notes 2 and 3): 67°C/W; (6)Operating virtual junction temperature, TJ:150°C; (7)Storage temperature range, Tstg:-65°C to 150°C.
Features
TL598CN feature: (1)Complete PWM Power-Control Function; (2)Totem-Pole Outputs for 200-mA Sink or Source Current; (3)Output Control Selects Parallel or Push-Pull Operation; (4)Internal Circuitry Prohibits Double Pulse at Either Output; (5)Variable Dead-Time Provides Control Over Total Range; (6)Internal Regulator Provides a Stable 5-V Reference Supply, Trimmed to 1% Tolerance; (7)On-Board Output Current-Limiting Protection; (8)Undervoltage Lockout for Low-VCC Conditions; (9)Separate Power and Signal Grounds.
