MP2209DL-LF-P Equivalent & Substitute Parts

Part Overview

The MP2209DL-LF-P is a buck switching regulator IC manufactured by Monolithic Power Systems, designed for positive adjustable output applications. This device operates as a step-down converter with a single adjustable output ranging from 0.8V to 14.4V, capable of delivering 2A of output current. The part is classified as "Not For New Designs," indicating it has reached end-of-life status. Finding equivalent or substitute parts is necessary for applications requiring continued supply or for new designs seeking functionally similar alternatives with active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP2209DL-LF-P is evaluated based on the following critical parameters:

• Package Compatibility: Both main and substitute parts must use the 14-VFDFN Exposed Pad package to ensure PCB layout compatibility without redesign.
• Topology and Function: The main part operates as a buck (step-down) converter with adjustable output. Substitute parts may employ different topologies (such as buck-boost) provided they can deliver the required output voltage and current range within the application's input voltage constraints.
• Output Voltage Range: The substitute must support the output voltage requirements of the target application. The MP2209DL-LF-P provides adjustable output from 0.8V to 14.4V.
• Output Current: The substitute must meet or exceed the 2A output current requirement.
• Input Voltage Range: The substitute must accept input voltages within the application's supply range (3V to 16V for the main part).
• Thermal and Compliance Requirements: Operating temperature range (-40°C to 85°C) and RoHS3 compliance must be maintained.

Parameter Comparison

Engineering Selection Recommendations

The TPS63021DSJR from Texas Instruments shares the same 14-VFDFN Exposed Pad package as the MP2209DL-LF-P, enabling direct PCB footprint compatibility. Both devices maintain ROHS3 compliance and operate across the -40°C to 85°C temperature range.

Key differences exist in topology and output configuration. The MP2209DL-LF-P is a buck converter with adjustable output voltage, while the TPS63021DSJR is a buck-boost converter with fixed 3.3V output. The TPS63021DSJR provides higher output current capability (4.6A switch current versus 2A) and operates at a higher switching frequency (2.4MHz versus 600kHz).

The TPS63021DSJR is classified as an active product, making it suitable for new designs. Selection of this substitute is appropriate only for applications requiring a fixed 3.3V output within the 1.8V to 5.5V input voltage range. Applications requiring adjustable output voltage or input voltages exceeding 5.5V require alternative substitutes or continued use of the MP2209DL-LF-P from existing inventory.

Frequently Asked Questions (FAQ)

Q: Can the TPS63021DSJR directly replace the MP2209DL-LF-P in all applications?

A: No. While both devices share the same 14-VFDFN Exposed Pad package, the TPS63021DSJR has a fixed 3.3V output, whereas the MP2209DL-LF-P provides adjustable output from 0.8V to 14.4V. Substitution is only valid for applications specifically requiring 3.3V output. Additionally, the TPS63021DSJR input voltage range (1.8V to 5.5V) is narrower than the MP2209DL-LF-P (3V to 16V).

Q: What are the package compatibility implications?

A: Both parts use the 14-VFDFN Exposed Pad package with identical pinout compatibility. PCB layout and footprint modifications are not required for package substitution. However, the different topologies and output configurations may require changes to external component values and circuit design.

Q: Why is the MP2209DL-LF-P marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. Existing inventory may remain available, but long-term supply cannot be guaranteed. New designs should evaluate active alternatives such as the TPS63021DSJR or other current-generation regulators.

Q: What is the significance of the higher switching frequency in the TPS63021DSJR?

A: The TPS63021DSJR operates at 2.4MHz compared to the MP2209DL-LF-P at 600kHz. Higher switching frequency allows for smaller external filter components but may increase electromagnetic interference (EMI) considerations in the circuit design.

Q: Are there compliance differences between these parts?

A: Both devices are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution from a regulatory standpoint.
