SP7614EC6-L/TR

Overview

The SP7614EC6-L/TR is a low dropout linear LED driver manufactured by Sipex. It provides matched current sources for parallel-connected LEDs, supporting up to two channels with a maximum steady-state current of 80mA per channel. The device features integrated PWM and analog brightness control, along with an enable/shutdown pin that reduces shutdown current to less than 0.01µA. It operates in lead-free SC-70 packages compliant with RoHS standards.

Feature Summary

• Provides matched current sources for any color LED
• Supports both PWM and analog brightness control
• Features passive shutdown with ultra-low current consumption

Applications

• Handheld computers
• LCD display modules
• Keyboard backlighting
• LCD backlighting

Procurement Notes

Verify the manufacturer designation as Sipex or Exar, noting corporate acquisitions may affect labeling. Confirm the package type matches the SC-70 specification and ensure the suffix indicates lead-free compliance. Cross-reference the specific voltage and current ratings against the official datasheet to confirm compatibility with the target LED load requirements.

Selection Notes

Select this component when driving parallel LEDs requiring precise current matching without external switching noise. The integrated enable function simplifies power management compared to discrete solutions. Ensure the application does not exceed the 80mA per channel limit and verify that the SC-70 package size fits the PCB layout constraints.

Part Context

This part belongs to the SP761x series of low dropout LED drivers designed for portable electronics. It serves as a cost-effective alternative to complex switching regulators for backlight applications. The series includes variants like the SP7612 for three-channel configurations, offering flexibility for different display module designs.
