Overview
The NCL31000MNSTWG is an intelligent LED driver IC from onsemi, designed for high-performance lighting applications. It features a buck topology with a single output capable of delivering up to 3 A. The device operates within an input voltage range of 21.5 V to 57 V and supports output voltages from 4 V to 38 V. Switching frequency is adjustable between 44.4 kHz and 1 MHz. Packaged in a QFN-48 (7x7 mm) format, it supports PWM dimming and includes open LED protection. The component is rated for operation between -40°C and +125°C.
Feature Summary
- Intelligent LED driver with Visible Light Communication capability
- Precision dimming with high linearity and true dimming to zero current
- Integrated diagnostics for power metrology and system monitoring
- Supports both analog and PWM dimming interfaces
Applications
- Visible Light Communication systems
- Connected indoor and outdoor luminaire lighting
- Multi-channel managed lighting networks
- Theater and therapeutic lighting environments
- Information displays and backlighting solutions
Procurement Notes
Verify component status as the NCL31000 series has been designated obsolete by the manufacturer. Confirm availability through authorized distributors or remaining stock channels. Ensure design-in compliance with RoHS3 specifications. Check for moisture sensitivity level requirements during storage and handling. Validate that the specific suffix matches project interface needs before finalizing procurement orders.
Selection Notes
Select this component for applications requiring integrated intelligence beyond basic regulation. The NCL31000MNITWG variant offers I²C interface support instead of SPI. Consider the NCL31001 series if multi-channel output management is required. Evaluate thermal performance within the QFN-48 package constraints. Verify compatibility with existing microcontroller communication protocols for diagnostic data retrieval.
Part Context
Part of the NCL310xx family targeting advanced luminaire applications. Designed to replace traditional drivers with intelligent capabilities. Supports YellowDot™ compliance for visible light communication standards. Includes auxiliary DC-DC converters for peripheral power supply. Targets high-efficiency solutions exceeding 97% total system efficiency.
Replacement Considerations
NCL31000MNITWG serves as a parameter-equivalent alternative with I²C interface support. NCL31001MNITWG provides multi-channel enabled functionality for complex lighting setups. Both substitutes are available from onsemi. Verify pinout and interface compatibility when transitioning between variants.
