Product Description

The L5991D013TR from STMicroelectronics is a current-mode PWM Controller optimized for offline power supplies and DC-DC conversion. Operating within a voltage range of 8V to 20V, it supports industrial environments with a temperature range of -40°C to 150°C. The device features a single PWM output to directly drive external power MOSFETs or modules, integrating protections like over-voltage, over-current, and thermal shutdown. Widely used in industrial power systems, consumer electronics, and telecom equipment, it excels in precision regulation and compact design with minimal external components. Refer to the L5991D013TR Datasheet for configuration details, as setup complexity may require careful tuning. Parameters such as battery capacity, screen size, and detection distance are not applicable to this PWM-focused controller. Its reliability and robust integration make it a preferred choice for demanding applications.
