TL594CPW

The TL594CPW from Texas Instruments is a complete pulse-width-modulation (PWM) power-control circuit integrated onto a single chip. It is designed for power supply control, offering flexibility for various applications.

Key electrical specifications include an operating voltage range of 7V to 40V and an adjustable frequency from 1kHz to 300kHz. The device supports multiple topologies such as Buck, Boost, Flyback, and Push-Pull configurations. It features control functions like dead time control and frequency control, along with uncommitted outputs capable of 200mA sink or source current.

This PWM controller incorporates an internal 5V reference supply with 1% precision and undervoltage lockout (UVLO) for low-voltage conditions. The output transistors provide either common-emitter or emitter-follower capability, allowing for single-ended or push-pull operation. The architecture prevents double pulsing at either output.

The TL594CPW is supplied in a 16-TSSOP package suitable for surface mounting. Its operating temperature range is 0°C to 70°C (TA). This component is suitable for applications including white goods, power supplies (AC/DC, isolated, with or without PFC), server PSUs, and solar power inverters.
