Overview
The NCR420UX is a single-channel LED lighting driver IC manufactured by Nexperia, designed for constant current regulation. It supports both Boost and Buck topologies with an output current capability of 150 mA. The device operates within a supply voltage range up to 40 V and delivers an output voltage of 40 V. It functions at a working frequency of 10 kHz and is housed in a TSOP-6 (SOT-457/SC-74) surface-mount package. The component is rated for an operating temperature range from -55°C to +150°C.
Feature Summary
- Provides constant current regulation for LED loads
- Supports flexible Boost and Buck converter topologies
- Integrated internal switching element for simplified circuit design
Applications
- LED lighting driver circuits
- General-purpose LED illumination systems
Procurement Notes
Verify the specific suffix 'X' against the official Nexperia datasheet to confirm packaging details such as reel or cut tape specifications. Ensure the ordering code matches the required quantity format. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement orders.
Selection Notes
Select this component when a single-channel solution with 150 mA output current is required for LED applications. The choice between Buck or Boost topology depends on the input-to-output voltage relationship in the target design. Verify that the TSOP-6 package footprint fits the PCB layout constraints and that the thermal performance meets the system requirements within the specified temperature range.
Part Context
This part belongs to the Nexperia LED Drivers product category, specifically under LED Lighting Drivers. It is classified as a Driver IC within the broader semiconductor portfolio. The NCR420UX is distinct from other variants like the NCR405UX, which offers lower output current capabilities, and differs from bipolar transistors sharing similar alphanumeric prefixes.
Replacement Considerations
The NCR405UX serves as a related variant within the same family but provides only 50 mA output current. Designers requiring higher current drive must verify that the load specifications align with the 150 mA limit of the NCR420UX. No direct cross-manufacturer substitutes are confirmed in the provided data.
