LM3495MTC Equivalent & Substitute Parts

Part Overview

The LM3495MTC is a buck regulator positive output step-down DC-DC controller IC manufactured by Texas Instruments in a 16-TSSOP package. This device functions as a transistor driver for step-down topology applications with emulated peak current mode control. The LM3495MTC is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity. Substitute parts must maintain identical electrical specifications, package configuration, and control feature compatibility to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitute parts for the LM3495MTC are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key criteria:

Topology and Function: Buck regulator with transistor driver output for step-down DC-DC conversion Electrical Specifications: Identical supply voltage range (2.9V ~ 18V), switching frequency capability (200kHz ~ 1.5MHz), duty cycle (96% max), and control features (current limit, frequency control, tracking) Package Configuration: 16-TSSOP surface mount package with identical physical dimensions Output Characteristics: Single positive output, single phase, with synchronous rectifier and clock sync capability Operating Temperature: -40°C ~ 125°C junction temperature range

Only parts meeting all these criteria are classified as direct substitutes. The LM3495MTC/NOPB qualifies as a direct substitute based on complete parameter alignment.

Parameter Comparison

Engineering Selection Recommendations

The LM3495MTC/NOPB is a direct functional equivalent to the obsolete LM3495MTC. Both parts share identical electrical specifications, package configuration, and control feature sets. The primary distinction is product status: the LM3495MTC is obsolete while the LM3495MTC/NOPB maintains active status with National Semiconductor, ensuring ongoing availability and supply chain continuity.

For new designs or replacement procurement, the LM3495MTC/NOPB is the appropriate selection. Both parts carry identical export classification (ECCN: EAR99) and tariff codes (HTSUS: 8542.39.0001), with no compliance or regulatory barriers to substitution. The 16-TSSOP package remains consistent across both parts, requiring no PCB layout modifications.
