TL594CDR Description

Short technical summary and product information.

The TL594CDR is a pulse-width-modulation (PWM) control circuit from Texas Instruments, designed for power supply control applications. It integrates essential functions like two error amplifiers, an adjustable oscillator, a dead-time control comparator, and output control circuitry onto a single chip.

 

This controller operates with an input voltage range of 7V to 40V and offers an adjustable switching frequency from 1kHz up to 300kHz. It supports multiple topologies including Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations. The device features a maximum duty cycle of 97% and provides control features such as dead time control and frequency control.

 

Packaged in a 16-SOIC surface mount configuration, the TL594CDR is suitable for various power supply designs, including AC/DC isolated supplies with or without PFC, server PSUs, and solar power inverters. Its architecture prohibits double pulsing at either output and includes undervoltage lockout for low-VCC conditions.
