Product Description

STMicroelectronics L5970D013TR is a high-performance 5-channel step-down switching buck converter designed for efficient power regulation in electronic systems. Supporting up to 1A output current, it provides adjustable output voltage from 1.2V to 35V, making it flexible for varied industrial and commercial power supply requirements.

The device incorporates an internal P-Channel D-MOS transistor with a typical Rdson of 250 mΩ, reducing external component size and improving efficiency. With a fixed 275 kHz switching frequency, the L5970D013TR ensures predictable performance and reduced electromagnetic interference.

Its low quiescent current of 2.5 mA aids in maintaining low power consumption during operation. The wide input voltage range from 4.4V to 36V facilitates its use in 5V bus systems and beyond, ideal for computing and embedded applications.

The compact SOIC 8-pin package (5 mm length, 4 mm width, 1.25 mm height) suits surface mounting on PCBs, optimizing space in tight designs. Advanced features include pulse-by-pulse current limiting, feedback disconnection protection, synchronization capabilities, and thermal shutdown, ensuring robust protection and operation longevity.

Switching regulator type with fixed frequency operation at 275 kHz. Output current capacity up to 1A with adjustable voltage from 1.2V to 35V. Internal P-Channel D-MOS transistor minimizes component count. Low quiescent current of 2.5 mA optimizes efficiency.

Wide input voltage range from 4.4V to 36V for versatile usage. Compact surface mount SOIC 8-pin package (5x4x1.25 mm). Comprehensive protection: thermal shutdown, current limiting, feedback disconnection protection. Operating temperature range -40°C to 150°C.

This converter is well suited for industrial electronics, power management in computing devices, embedded systems, and other applications requiring regulated DC output with efficient power conversion. It complies with RoHS standards for environmental safety.
