Overview
The Intersil EL7801ALZ-T7 is a high-power LED driver controller featuring an integrated 36V FET. It operates as a DC-DC controller with PWM dimming capability, supporting up to 1A output current. The device is housed in a 20-QFN (5x5) surface-mount package and functions within a supply voltage range of up to 16V, generating output voltages from 0V to 32V. It is designed for driving multiple high-power LEDs in series.
Feature Summary
- Integrates a high-voltage power FET for compact design
- Supports pulse-width modulation for precise brightness control
- Capable of driving multiple high-power LEDs in series configuration
Applications
- LED backlighting systems
- General lighting applications
Procurement Notes
Verify the specific suffix 'T7' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as listed in official documentation. Ensure the supplier provides the original datasheet for the EL7801 family to validate electrical characteristics against your circuit requirements before finalizing procurement.
Selection Notes
Select this component for designs requiring a single-chip solution for high-power LED strings. The integrated FET reduces external component count compared to discrete solutions. Verify that the required output voltage does not exceed the 32V limit and that the input supply remains within the specified operational range for stable performance.
Part Context
This part belongs to the EL7801 series of LED drivers manufactured by Intersil, now part of Renesas Electronics. The series is characterized by high-efficiency switching regulators tailored for backlight and lighting applications. The EL7801ALZ-T7 represents a specific packaged variant optimized for surface-mount assembly in consumer electronics.
Replacement Considerations
Check for direct pin-compatible substitutes within the EL7801 family. Verify if newer Renesas equivalents offer updated thermal or efficiency specifications while maintaining the same 20-QFN footprint and functional interface.
