Overview
The NCR420PASX is a single-channel LED lighting driver IC manufactured by Nexperia. It integrates Boost topology for constant current regulation with an output current capability of 250 mA. The device supports a maximum input and output voltage of 16 V, operating at a fixed frequency of 10 kHz. Designed for surface-mount installation in the SOT-1118 (HUSON6) package, it functions within a temperature range of -55°C to +150°C, with a maximum power dissipation of 1.8 W.
Feature Summary
- Integrates Boost converter topology for efficient step-up LED driving
- Provides regulated constant current output for stable LED brightness
- Supports high junction temperatures up to 150°C for robust operation
Applications
- LED lighting modules requiring step-up voltage conversion
- Portable battery-powered illumination devices
- General solid-state lighting applications
Procurement Notes
Verify the specific suffix 'X' corresponds to the required tape-and-reel packaging configuration as defined in the official datasheet. Confirm that the SOT-1118 footprint matches the target PCB design. Ensure supply chain sources provide valid RoHS compliance documentation consistent with manufacturer specifications.
Selection Notes
Select this component when a compact Boost topology solution is required for low-voltage LED strings. The 250 mA output current suits moderate-power applications. Consider the 16 V voltage limit and 10 kHz switching frequency constraints against system requirements. The wide operating temperature range allows use in demanding environments.
Part Context
This part belongs to the NCR series of LED drivers from Nexperia, designed for cost-effective and space-constrained lighting solutions. It complements other variants like the NCR420UX and NCR420ZX, which offer similar functionality but differ in package types such as TSOP-6 or SOT-223, allowing flexibility in mechanical design.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Engineers should consult official Nexperia documentation for potential cross-reference options.
