SP7600EN2-L/TR

Overview

The SP7600EN2-L/TR is a non-synchronous buck LED lighting driver IC manufactured by MaxLinear. It operates within an input voltage range of 4.5 V to 29 V and delivers a low-level output current of 2 A. The device supports analog and PWM dimming for precise light control. It is housed in an 8-HSOIC package and functions reliably across a temperature range of -40°C to +125°C. This component is designed for high-power applications requiring efficient DC-DC regulation.

Feature Summary

• Integrates a non-synchronous buck converter topology for efficient power conversion
• Supports both analog and pulse-width modulation (PWM) dimming methods
• Capable of driving high-power loads with up to 2 A output current

Applications

• LED lighting systems requiring series-connected LEDs
• High-power LED drivers utilizing non-synchronous buck topologies
• General-purpose DC-DC step-down regulation for LED arrays

Procurement Notes

Verify the obsolete status of this part number before initiating any design-in process, as it may no longer be in active production. Confirm that the 8-HSOIC package dimensions match your PCB footprint requirements. Ensure that the 29 V maximum input voltage rating aligns with your system's supply rails. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a non-synchronous buck architecture is preferred or required for cost-sensitive LED driver designs. It is suitable for applications where the input voltage does not exceed 29 V and output currents around 2 A are sufficient. Consider the wide operating temperature range for industrial or automotive environments. Verify compatibility with existing analog or PWM control signals from the host microcontroller.

Part Context

This device belongs to the SP7600 series of LED lighting drivers from MaxLinear. The manufacturer acquired Exar, which originally developed many of these interface and power management products. The SP7600 series focuses on providing integrated solutions for LED illumination, combining control logic with power switching elements in compact packages.
