LM2792LDX-L/NOPB

Overview

The LM2792LDX-L/NOPB is a dual-output LED driver IC manufactured by Texas Instruments. It utilizes a switched capacitor (charge pump) topology with an internal switch to regulate output current. The device supports both analog and PWM dimming methods for backlight applications. It operates within an input voltage range of 3V to 5.8V and features a switching frequency of 1.1MHz or 1.8MHz depending on the specific configuration variant. The component is housed in a 10-WSON (3x3 mm) surface-mount package, suitable for space-constrained designs.

Feature Summary

• Dual-output capability for independent LED channel control
• Integrated charge pump topology with internal switches
• Supports both analog and pulse-width modulation dimming techniques

Applications

• Backlight regulation for mobile devices
• LED illumination systems requiring analog dimming
• PWM-controlled lighting circuits

Procurement Notes

Verify the exact suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with specific dimming requirements. Confirm the operating temperature range and package dimensions match the target PCB layout. Ensure supply chain sources provide genuine components with valid traceability documentation.

Selection Notes

Select this component when dual-channel LED driving is required without external inductors. Consider the 1.1MHz or 1.8MHz switching frequency options based on electromagnetic interference constraints. Evaluate the 3V to 5.8V input voltage window against the system power supply rails to ensure stable operation under all load conditions.

Part Context

This part belongs to the LM2792 family of LED drivers from Texas Instruments. It is designed as a compact solution for regulating LED current in portable electronics. The WSON package allows for low-profile mounting on printed circuit boards, supporting modern miniaturization trends in consumer electronic hardware design.

Replacement Considerations

Consult official substitution lists for equivalent dual-output charge pump LED drivers. Verify pinout compatibility and electrical specifications before replacing existing components in production designs.
