SP7600EN2-L

Overview

The SP7600EN2-L 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 single-channel step-down DC-DC converter topology optimized for LED loads
• Supports both analog and pulse-width modulation (PWM) dimming methods for brightness adjustment
• Features internal switching elements to reduce external component count and board space

Applications

• High-power LED lighting systems
• General-purpose DC-DC conversion tasks
• LED drivers requiring wide input voltage ranges

Procurement Notes

Verify the specific suffix 'L' against the manufacturer's official documentation to confirm pinout and electrical specifications, as variations may exist within the series. Confirm RoHS compliance status through the latest datasheet revision. Note that this part number is listed as obsolete or end-of-life by major distributors; ensure alternative sourcing strategies are in place for production continuity.

Selection Notes

Select this component when a non-synchronous buck architecture is preferred for cost-sensitive LED applications. Ensure the design accommodates the 2 A output current limit and the 29 V maximum input voltage. Verify thermal management requirements for the HSOIC-8 package given the operating temperature range up to 125°C. Confirm compatibility with the required dimming signal type, whether analog or PWM.
