Texas Instruments TL284X.TL384X Data Sheet
Summary
These high-performance integrated circuits are essential for implementing fixed-frequency current-mode control in off-line or DC-to-DC power converters. Designed to minimize external components, this series provides advanced features such as undervoltage lockout (UVLO) and a powerful totem-pole output stage capable of managing high peak currents. The manual details the technical specifications across the TL284x and TL384x families, helping engineers select the precise device based on required UVLO thresholds and operating temperature range for robust power management solutions.

Frequently Asked Questions
What is the typical start-up current for the Undervoltage Lockout circuit?
The UVLO features a small start-up current of less than 1 mA.
How do I restrict the output duty cycle range down to 0-50%?
This is achieved by using an internal toggle flip-flop, which blanks the output off every other clock cycle.
What temperature range are the TL284x devices rated for?
The TL284x series characteristics cover operation from -40°C up to 85°C.
Are these control circuits suitable for automotive use without specific designators?
No, they are not intended for automotive applications unless the product is specifically designated as compliant with ISO/TS 16949 requirements.
