TL594INSR Description

Short technical summary and product information.

The TL594INSR from Texas Instruments is a versatile pulse-width-modulation (PWM) control circuit designed for power supply applications. This integrated circuit incorporates essential functions for building robust power control systems, including two error amplifiers, an adjustable oscillator, a dead-time control comparator, and output control circuitry.

 

Key electrical specifications include an operating voltage range of 7V to 40V and an adjustable operating frequency from 1kHz to 300kHz. The device offers a maximum duty cycle of 97% and provides 200mA sink or source current capability from its uncommitted outputs. It supports multiple topologies such as Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations, with features like dead-time control and frequency control for precise regulation.

 

The TL594INSR is housed in a 16-SOIC package, suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C. The integrated 5V reference supply is trimmed to 1% precision, and the device includes undervoltage lockout (UVLO) for low-VCC conditions, ensuring reliable operation. Its architecture prohibits double pulsing at either output, enhancing system stability.
