Product Summary
The TL594CDR is a pulse-width-modulation control circuit which incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control circuit on a single chip. Designed primarily for power-supply control, this device offers the systems engineer the flexibility to tailor the power-supply control circuitry to a specific application. The TL594CDR contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, a 5-V regulator with a precision of 1%, an undervoltage lockout control circuit, and output control circuitry.
Parametrics
TL594CDR absolute maximum ratings: (1)Supply voltage, VCC: 41 V; (2)Amplifier input voltage: VCC + 0.3 V; (3)Collector output voltage: 41 V; (4)Collector output current: 250 mA; (5)Package thermal impedance, θJA (see Notes 2 and 3): D package: 73℃/W; N package: 67℃/W; NS package: 64℃/W; PW package: 108℃/W; (6)Operating virtual junction temperature, TJ: 150℃; (7)Storage temperature range, Tstg: -65℃ to 150℃.
Features
TL594CDR features: (1)Complete PWM Power-Control Circuitry; (2)Uncommitted Outputs for 200-mA Sink or Source Current; (3)Output Control Selects Single-Ended 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%; (7)Circuit Architecture Allows Easy Synchronization; (8)Undervoltage Lockout for Low-VCC Conditions.
