SP7619ER-L

Overview

The SP7619ER-L is a linear LED driver IC manufactured by MaxLinear, Inc. It features two independent output channels capable of delivering up to 500 mA per channel. The device supports linear PWM dimming for precise brightness control and operates within a supply voltage range of 2.5 V to 5.5 V. It is housed in an 8-DFN (2x3 mm) package and is designed for operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

Dual-channel linear architecture with independent current control
Supports linear pulse-width modulation for smooth dimming applications
Compact surface-mount packaging suitable for space-constrained designs

Applications

LED backlighting systems requiring dual-zone control
Indicator lighting circuits with adjustable brightness
Portable electronic devices utilizing low-voltage LED arrays

Procurement Notes

Verify the specific suffix against official MaxLinear documentation to confirm pinout and electrical characteristics. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when dual independent LED channels are required within a compact footprint. Consider the linear topology limitations regarding efficiency at higher voltage differentials compared to switching regulators. Verify that the 500 mA per channel output current meets the target LED array specifications without exceeding thermal limits.

Part Context

This part belongs to the MaxLinear LED driver portfolio, formerly associated with Exar/Sipex product lines. It serves as a specialized power management solution for visual indication and illumination tasks. The series focuses on providing reliable current regulation for LEDs in consumer and industrial electronics where simplicity and cost-effectiveness are prioritized over high-efficiency switching architectures.
