TL594CPWR Description

Short technical summary and product information.

The TL594CPWR from Texas Instruments is a complete PWM power-control circuit on a single chip. It is designed for power supply control, offering flexibility for specific applications. Key features include uncommitted outputs capable of 200-mA sink or source current, and an output control that selects single-ended or push-pull operation.

 

This device incorporates two error amplifiers, an on-chip adjustable oscillator, a dead-time control comparator, a pulse-steering control flip-flop, a 5-V regulator with 1% precision, and an undervoltage lockout control circuit. The architecture prevents double pulsing at either output and provides variable dead time for control over the total range. It operates over a voltage range of 7V to 40V with an adjustable frequency from 1kHz to 300kHz.

 

The TL594CPWR is available in a 16-TSSOP package suitable for surface mounting. Its applications include white goods, power supplies (AC/DC, isolated, with or without PFC), server PSUs, solar micro-inverters, and telecom/server AC/DC supplies.
