Product Description
Texas Instruments LM22676TJE-5.0/NOPB is a high-performance 5-channel DC/DC converter designed for efficient and reliable step-down voltage regulation. It operates across a wide input voltage range from 4.5V to 42V and provides a fixed 5V output with a maximum current of 3A per channel. The device is housed in a compact TO-263 7-pin surface mount package with dimensions 10.16mm length, 9.85mm width, and 2mm height, making it ideal for space-constrained electronic designs.
This converter features a step-down switching topology with a nominal switching frequency of 500 kHz, which can be adjusted between 200 kHz and 1 MHz, allowing designers to optimize for efficiency and noise performance. Internal voltage mode control and compensation offer stable operation with low ESR ceramic capacitors, reducing external component count and simplifying PCB layout. An integrated boot diode and soft-start circuit enhance startup behavior and system protection.
Its extended operating temperature range from -40°C to 125°C makes it suitable for demanding industrial, automotive, and embedded applications. LM22676TJE-5.0/NOPB devices are fully WEBENCH® design enabled, providing designers with powerful tools for rapid prototyping and customization of power solutions.
Wide input voltage range supports applications from 4.5V to 42V. Fixed 5V output with 3A maximum current per channel. Step-down topology with adjustable switching frequency from 200 kHz to 1 MHz. Compact TO-263 7-pin surface mount package.
Full industrial temperature range from -40°C to 125°C. Integrated boot diode and soft-start for system reliability. Internally compensated voltage mode for low external component count. Compatible with low ESR ceramic capacitors for high stability.
WEBENCH® design enabled for easy design and prototyping.
