NCP5005SNT1G

Overview

The NCP5005SNT1G is a compact boost driver IC designed for white LED backlight applications. It operates within an input voltage range of 2.7 V to 5.5 V and delivers a maximum output current of 50 mA. The device utilizes Pulse Frequency Modulation (PFM) mode for high efficiency in current loop operation. It is housed in a 5-pin TSOP surface-mount package, suitable for space-constrained designs.

Feature Summary

• High-efficiency PFM boost converter topology
• Integrated current loop control for white LEDs
• Compact physical footprint

Applications

• White LED backlight drivers
• Portable electronic displays
• Mobile communication devices

Procurement Notes

Verify the specific suffix 'T1G' against official onsemi documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the component matches the exact 5-pin TSOP form factor required by the design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing circuits requiring a small solution size for driving white LEDs from low-voltage sources. The fixed 50 mA output capability suits standard single-LED or series configurations. Consider the 2.7 V minimum input requirement relative to the battery or supply rail characteristics.

Part Context

This part belongs to the NCP5005 family of LED drivers from onsemi. These devices are engineered specifically for portable electronics where power efficiency and board space are critical constraints. The family focuses on simple external component counts and reliable performance in boost converter topologies.

Replacement Considerations

Consult official substitution guides for compatible parts within the same product line. Verify pinout compatibility and electrical specifications before integrating alternative components.
