LM2795TL LED Driver IC Equivalent & Substitute Parts

Part Overview

The LM2795TL is a 4-output LED driver IC with integrated DC-DC regulator using switched capacitor (charge pump) topology. It provides analog and PWM dimming control for backlight applications with 20mA per-channel output capability. The LM2795TL is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

The LM2794TL/NOPB qualifies as a parametric equivalent to the LM2795TL based on the following matching criteria:

• Identical topology: Switched capacitor (charge pump) DC-DC regulator
• Matching electrical specifications: 4 outputs, 2.7V–5.5V supply range, 3.8V output, 20mA per channel, 515kHz frequency
• Identical dimming control: Analog and PWM dimming
• Identical package: 14-DSBGA (14-WFBGA, DSBGA)
• Identical mounting: Surface mount
• Identical operating temperature range: -30°C to 85°C
• Same application: Backlight LED driver

The primary distinction is product status and compliance: LM2794TL/NOPB is active and RoHS3 compliant, whereas LM2795TL is discontinued and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The LM2794TL/NOPB is the direct substitute for the discontinued LM2795TL. All electrical and mechanical parameters are identical, ensuring pin-for-pin and functional compatibility in backlight LED driver applications.

Selection advantages of LM2794TL/NOPB:

• Active product status ensures long-term availability and supply chain continuity
• RoHS3 compliance meets current environmental and regulatory requirements
• MSL rating of 1 (unlimited moisture sensitivity) provides superior handling and storage flexibility compared to MSL 3
• Tape & Reel packaging format supports automated assembly processes
• Higher inventory availability (3075 pcs vs. 1450 pcs) reduces procurement lead time

No design modifications, PCB layout changes, or firmware updates are required when transitioning from LM2795TL to LM2794TL/NOPB.

Frequently Asked Questions (FAQ)

Q: Can LM2794TL/NOPB replace LM2795TL in existing designs?

A: Yes. All electrical specifications, pin configurations, and functional characteristics are identical. Direct substitution is possible without design changes.

Q: What is the difference between LM2795TL and LM2794TL/NOPB?

A: The primary differences are product status (discontinued vs. active), RoHS compliance (non-compliant vs. RoHS3 compliant), MSL rating (3 vs. 1), and packaging format (bulk vs. Tape & Reel). Electrical and mechanical specifications are identical.

Q: Does the MSL rating difference affect compatibility?

A: No. MSL rating affects storage and handling conditions, not electrical performance or compatibility. MSL 1 (unlimited) is more favorable for supply chain management than MSL 3 (168 hours).

Q: Is the 14-DSBGA package identical between both parts?

A: Yes. Both parts use the same 14-DSBGA (14-WFBGA, DSBGA) surface mount package with identical pin assignments and mechanical dimensions.

Q: What applications are these parts suitable for?

A: Both parts are designed for backlight LED driver applications requiring 4-channel output with analog and PWM dimming control in the 2.7V–5.5V supply range.

Q: Are there any certifications or compliance differences?

A: LM2794TL/NOPB is RoHS3 compliant and REACH unaffected. LM2795TL is RoHS non-compliant. Both share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
