TL594CN Description

Short technical summary and product information.

The TL594CN from Texas Instruments is a complete PWM power-control circuitry on a single chip. It is designed for power-supply control applications, offering flexibility to tailor control circuitry to specific needs.

 

Key features include uncommitted outputs capable of 200-mA sink or source current, output control for single-ended or push-pull operation, and internal circuitry to prevent double pulsing. It also provides variable dead time control for total range management and an internal regulator for a stable 5-V reference supply with 1% precision. The device incorporates undervoltage lockout (UVLO) for low-VCC conditions.

 

This PWM controller supports multiple topologies including Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull. It operates over a voltage range of 7V to 40V with an adjustable switching frequency from 1kHz up to 300kHz. The maximum duty cycle is 97%.

 

The TL594CN is available in a 16-PDIP package and is designed for through-hole mounting. Its operating temperature range is 0°C to 70°C (TA).
