Overview
The PAM2863ECR is a single-channel LED lighting driver IC from Diodes Incorporated, designed for high-efficiency buck conversion. It integrates an internal 40V NDMOS switch and supports input voltages from 4.5 V to 40 V. The device delivers up to 2 A output current with adjustable voltage output. Operating frequencies range from 233 kHz to 1 MHz within an operating temperature range of -40°C to +85°C. It features PWM dimming, open LED protection, and soft start functionality in an SOP-8 package.
Feature Summary
- Integrates an internal 40V NDMOS switch to reduce external component count
- Supports both analog and PWM dimming methods for brightness control
- Includes open LED protection and soft start capabilities
Applications
- LED lighting driver circuits
- Buck converter applications requiring integrated switching
- General-purpose LED illumination systems
Procurement Notes
Verify the specific suffix 'ECR' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with moisture sensitivity levels and soldering profiles required for SOP-8 surface mount assembly. Cross-reference ordering information directly with Diodes Incorporated documentation to avoid discrepancies.
Selection Notes
Select this component when a buck topology is required for LED driving with an integrated power switch. It is suitable for designs needing up to 2 A output current and input voltages up to 40 V. Consider the SOP-8 package constraints and the need for external inductors and capacitors based on the chosen switching frequency.
Part Context
This part belongs to the PAM2863 series of LED drivers manufactured by Diodes Incorporated. It is categorized under LED Lighting Drivers and DC/DC converters. The ECR suffix typically denotes the specific packaging configuration, such as cut tape or reel options, distinct from other variants in the same functional family.
Replacement Considerations
Consult official substitution guides for compatible parts within the PAM2863 series or similar buck LED drivers from Diodes Incorporated. Verify pinout compatibility and electrical parameters before replacing.
