Overview
The NCR420ZX is an LED lighting driver IC manufactured by Nexperia, designed for constant current regulation in illumination applications. It features a single output channel capable of delivering up to 150 mA and supports both Boost and Buck topologies. The device operates with a supply voltage range up to 40 V and includes a fixed operating frequency of 10 kHz. It is housed in a SOT-223-3 surface-mount package and offers a power dissipation rating of 1.8 W, functioning within a temperature range of -55°C to +150°C.
Feature Summary
- Provides constant current output for stable LED driving
- Supports flexible Boost and Buck converter topologies
- Integrates single-channel control for simplified circuit design
Applications
- LED lighting driver circuits
- General regulation functions
- Voltage reference applications
Procurement Notes
Verify the specific suffix 'ZX' against official Nexperia documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the selected variant matches the required SOT-223-3 footprint and thermal characteristics for your PCB layout. Cross-reference the datasheet revision date to confirm compliance with current RoHS standards and material declarations before finalizing procurement orders.
Selection Notes
Select this component when designing LED drivers requiring a single output channel with integrated constant current control. Consider the 150 mA output limit and 40 V maximum voltage constraints relative to the load requirements. Evaluate the 1.8 W power dissipation capability against thermal management strategies, as the SOT-223-3 package may require adequate copper area for heat spreading in high-duty cycle applications.
Part Context
This part belongs to Nexperia's portfolio of LED lighting driver ICs, specifically engineered for efficient light source regulation. It complements other discrete components by providing integrated switching control, reducing external component count compared to discrete solutions. The device targets compact lighting modules where space efficiency and reliable constant current performance are critical design parameters.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings if considering alternative manufacturers for this specific topology.
