Product Description
Texas Instruments LM22680MR-ADJ/NOPB is a high-performance buck converter designed for DC-DC step-down voltage regulation. It supports a wide input voltage range from 4.5V to 42V and delivers a stable output voltage of 37V with a current capability of up to 2 A. Its surface mount HSOP package with compact dimensions (4.9 mm length, 3.9 mm width, 1.7 mm depth) makes it suitable for dense circuit board layouts in industrial electronics.
This converter operates efficiently at 90%, minimizing power loss and thermal dissipation, which is beneficial for prolonged device reliability. The device is stable when used with low Equivalent Series Resistance (ESR) ceramic capacitors, enhancing output voltage quality with minimal ripple and noise.
The LM22680 series features an integrated boot diode and soft-start circuitry to improve startup performance and reduce inrush current during power-up. Additionally, the switching frequency set at 500 kHz is adjustable between 200 kHz and 1 MHz, allowing design flexibility for different electromagnetic interference and efficiency requirements.
Operating temperature range from -40°C to 125°C ensures reliability in harsh industrial conditions. The device uses an internally compensated voltage mode control scheme to minimize external components, resulting in a reduced bill of materials (BOM) for ease of application.
The product is fully WEBENCH Design enabled by Texas Instruments, providing powerful design tools for rapid prototyping and optimization in applications such as industrial automation, power management, and embedded systems.
Wide input voltage from 4.5V to 42V. High efficiency of 90% for power saving. Compact HSOP surface mount package. Operating temperatures from -40°C to 125°C. Stable with low ESR ceramic capacitors. Adjustable switching frequency (200 kHz to 1 MHz).
