LM2795TLX/NOPB

Overview

The LM2795TLX/NOPB is a current-regulated switched capacitor LED driver from Texas Instruments, designed for high-efficiency white LED applications. It features four independent output channels capable of delivering up to 20mA per channel with a regulated output voltage of 3.8V. Operating at a switching frequency of 515kHz, the device supports both analog and PWM dimming methods for precise brightness control. The component functions within an input supply range of 2.7V to 5.5V and operates across a temperature range of -30°C to 85°C.

Feature Summary

• Integrates four independent current-regulated output channels for multi-LED driving
• Supports simultaneous analog and PWM dimming control mechanisms
• Utilizes switched capacitor topology for efficient power conversion without inductors

Applications

• Backlight illumination systems
• White LED lighting drivers
• Portable electronic display backlighting

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS standards as defined by Texas Instruments. Confirm that the 'TLX' designation indicates tape-and-reel packaging suitable for automated surface-mount assembly. Cross-reference the manufacturer datasheet to ensure the part meets the required thermal and electrical specifications for the intended operating environment before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring multiple independently controlled LED channels from a single IC. It is appropriate for space-constrained portable devices where inductor-based solutions are undesirable. Ensure the application requires the specific 515kHz switching frequency and 3.8V output regulation profile provided by this switched capacitor architecture.

Part Context

This device belongs to the LM2795 family of LED drivers manufactured by Texas Instruments. It is functionally related to the LM2794 series, sharing similar switched capacitor technologies but differing in channel count and specific configuration options. The NOPB suffix denotes a non-Pb (lead-free) package variant compliant with environmental directives.

Replacement Considerations

Public documentation identifies the LM2794TL/NOPB as a parameter-equivalent substitute option.
