NCP5007SNT1G

Overview

The NCP5007SNT1G is a compact boost driver designed for backlight LED applications. It operates with an input voltage range of 2.7V to 5.5V and supports output currents up to 300mA. The device integrates a 1.2MHz fixed-frequency PWM controller and features adjustable current regulation via an external resistor. Key electrical parameters include a quiescent current of 40µA in shutdown mode and a typical efficiency exceeding 90%. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated high-efficiency boost converter topology optimized for LED driving
• Fixed switching frequency eliminates need for external inductor tuning
• Compact package design suitable for space-constrained mobile devices

Applications

• LCD backlight power supply for mobile phones
• LED illumination for portable media players
• Backlight drivers for small form-factor displays

Procurement Notes

Verify the specific suffix 'T1G' corresponds to the tape-and-reel packaging configuration as documented in the official onsemi datasheet. Confirm that the component meets RoHS compliance standards required for your assembly process. Cross-reference the manufacturer part number against the latest revision history to ensure compatibility with existing design files.

Selection Notes

Select this component when designing low-power LED backlight systems requiring minimal external components. It is suitable for applications where board space is limited and high efficiency is critical. Ensure the input voltage source remains within the specified 2.7V to 5.5V range to maintain stable operation and prevent damage to the internal circuitry.

Part Context

This part belongs to the NCP500 series of LED drivers from onsemi, specifically engineered for portable electronics. It complements other power management solutions by providing dedicated backlight control. The series focuses on integrating power switches and control logic into a single small footprint to simplify PCB layout and reduce overall system cost.

Replacement Considerations

Consult the official onsemi substitution guide for verified alternatives. Direct pin-to-pin replacements may exist within the same family but require verification of thermal and electrical specifications.
