LM3200TL/NOPB Equivalent & Substitute Parts

Part Overview

The LM3200TL/NOPB is a buck switching regulator IC from Texas Instruments designed for positive adjustable output applications. This device delivers 500mA output current with an adjustable output voltage range of 0.8V to 3.6V, operating from a 2.7V to 5.5V input supply. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM3200TL/NOPB is determined by the following critical parameters:

• Topology & Function: Buck switching regulator with step-down capability
• Output Configuration: Positive adjustable output
• Switching Frequency: 2MHz operation
• Synchronous Rectifier: Integrated synchronous rectification
• Input Voltage Range: Minimum 2.7V support
• Output Voltage Adjustability: Minimum 0.8V or lower output capability
• Compliance: ROHS3 and REACH compliance maintained

The TLV62080DSGR qualifies as a manufacturer-recommended substitute based on these parameters. While it offers enhanced specifications (higher output current and extended temperature range), it maintains functional compatibility with the core buck regulator topology and control characteristics required for LM3200TL/NOPB replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The TLV62080DSGR is the manufacturer-recommended substitute for the obsolete LM3200TL/NOPB. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. The substitute part offers superior specifications across output current capacity (1.2A versus 500mA) and extended lower temperature operation (-40°C versus -25°C minimum), while maintaining identical switching frequency and synchronous rectification architecture.

Package differences exist between the two devices (10-WFBGA for LM3200TL/NOPB versus 8-WFDFN for TLV62080DSGR), requiring PCB layout modification. The TLV62080DSGR's broader output voltage range (0.5V to 4.0V) and lower minimum input voltage (2.5V) provide additional design flexibility compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can the TLV62080DSGR directly replace the LM3200TL/NOPB without circuit modifications?

A: The TLV62080DSGR is functionally compatible as a buck regulator with adjustable output, but package differences require PCB redesign. The 10-WFBGA package of the LM3200TL/NOPB differs from the 8-WFDFN package of the TLV62080DSGR, necessitating layout changes. Feedback network component values may require adjustment based on the specific output voltage and current requirements of your application.

Q: What are the key compatibility criteria for substitution?

A: Substitution is based on buck topology, positive adjustable output configuration, 2MHz switching frequency, synchronous rectification, and compliance certifications. Input voltage range overlap (2.7V to 5.5V for LM3200TL/NOPB; 2.5V to 5.5V for TLV62080DSGR) and output voltage adjustability (0.8V minimum for LM3200TL/NOPB; 0.5V minimum for TLV62080DSGR) determine functional equivalence.

Q: Why is the LM3200TL/NOPB classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Texas Instruments. The TLV62080DSGR, classified as active, represents the current generation solution with enhanced performance characteristics and ongoing manufacturer support.

Q: Are there compliance or certification differences between the two parts?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. No compliance degradation occurs with substitution. Both carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What output current applications are suitable for each part?

A: The LM3200TL/NOPB is rated for 500mA maximum output current. The TLV62080DSGR supports 1.2A output current, providing headroom for higher-power applications. Applications requiring less than 500mA output current are compatible with both devices.
