Product Description

The STMicroelectronics L4971 is a monolithic 5-channel DC/DC adjustable step-down converter designed for efficient power management applications. It accepts an input voltage range from 8V to 55V and can regulate output voltages between 3.3V and 50V, suitable for multi-rail power requirements in industrial and electronic equipment.

This device supports up to 1.5A maximum output current per channel, making it ideal for power supplies in communication devices, industrial control systems, and embedded electronics. Its step-down (buck) topology enables efficient voltage regulation with minimal power loss. The included switching frequency of 0.3MHz ensures reduced electromagnetic interference and compact external component sizing, contributing to overall system miniaturization.

Packaged in a reliable through-hole 8-pin PDIP format, the L4971 allows easy integration and mounting on standard printed circuit boards (PCBs). Its operating temperature range from -40°C to 150°C makes it suitable for harsh environments and demanding industrial applications. The compact physical dimensions (10.92 mm length x 6.6 mm width x 3.32 mm height) optimize board space usage without compromising thermal performance.

This power management IC finds applications widely in laboratory electronics, industrial automation, instrumentation, HVAC control systems, and power supply design. Its multiple outputs provide flexibility for devices requiring multiple voltage levels from a single input source.

Maximum output voltage: 50V adjustable per channel. Input voltage range: 8V minimum to 55V maximum. Maximum output current of 1.5A per output channel. Step-down converter topology for efficient voltage regulation. Through-hole mounting package (PDIP) with 8 pins.

Operating temperature range from -40°C to 150°C. Compact device size facilitates integration into dense electronic assemblies. Manufactured in China, ensuring adherence to quality standards.
