NCP5604BMTR2G

Overview

The NCP5604BMTR2G is a three-channel LED driver IC manufactured by onsemi, designed for high-efficiency lighting applications. It integrates a DC-DC switching regulator utilizing a charge pump topology to drive LEDs with up to 100mA per channel. The device supports both analog and PWM dimming methods for precise brightness control. Operating from a supply voltage between 2.7V and 5.5V, it delivers output voltages ranging from 4.8V to 6V. Packaged in a compact 16-QFN (3x3) format, it operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates a charge pump DC-DC converter for efficient LED power regulation
• Supports simultaneous analog and PWM dimming control inputs
• Features internal switches to minimize external component count
• Provides three independent current-regulated output channels

Applications

• LCD backlight illumination systems
• Camera flash units
• Portable electronic device lighting

Procurement Notes

Verify the part status carefully as this specific component is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure the package type matches the design requirements, specifically the 16-WFQFN with exposed pad configuration. Check for any product change notices that may affect long-term supply stability.

Selection Notes

Select this component when designing circuits requiring three-channel LED driving with integrated boost regulation. It is suitable for space-constrained designs due to the small QFN footprint. Consider the input voltage range and required output voltage headroom when integrating with battery-powered sources. Ensure compatibility with the system's dimming interface, whether analog voltage or pulse-width modulation signals are used.

Part Context

This part belongs to the NCP5604 series of LED drivers from onsemi. It is distinct from gate drivers like the NCP5104DR2G found in similar searches. The series focuses on low-voltage, multi-channel LED applications, differentiating itself from general-purpose power management ICs or transistor arrays.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative components must be selected based on functional equivalence, including channel count, current rating, and package dimensions.
