NCP5603MNR2

Overview

The NCP5603MNR2 is a high-efficiency charge pump converter designed as an LED driver IC. It features a single output with a maximum current of 200mA and supports PWM dimming. The device operates using a switched capacitor (charge pump) topology and is housed in a compact 10-DFN (3x3) package.

Feature Summary

• High efficiency charge pump conversion for LED driving applications
• Supports PWM dimming control for brightness adjustment
• Compact 10-DFN (3x3) surface-mount package

Applications

• White LED drivers
• LED lighting systems
• Portable electronic devices requiring efficient LED power management

Procurement Notes

Verify the specific suffix 'G' for RoHS compliance status, as datasheets may list variations. Confirm the package type matches the design requirement, as some listings reference standard versions while others specify lead-free variants. Ensure the supplier provides official onsemi documentation to validate authenticity and date codes.

Selection Notes

Select this component for applications requiring a small form factor and high efficiency in LED illumination. The 200mA output current suits low-power LED strings. Consider the 10-DFN package constraints for PCB layout. Verify thermal performance requirements against the package's dissipation capabilities.

Part Context

This part belongs to onsemi's LED driver portfolio, specifically focusing on charge pump converters. It is distinct from gate drivers like the NCP51563 series found in the same manufacturer's catalog. The NCP5603 series is optimized for white LED applications in space-constrained environments.

Replacement Considerations

Check for NCP5602 as a related variant in the same family. Verify pin compatibility and electrical specifications before substituting with other LED driver ICs from different manufacturers.
