FAQs

What is LMR33620BDDA?

The LMR33620BDDA is a 3.5V to 36V, 2A step-down DC-DC converter designed by Texas Instruments. It is ideal for applications requiring efficient voltage conversion, such as industrial power supplies, automotive and infotainment systems, and battery-powered equipment.

How Does LMR33620BDDA Work?

The LMR33620BDDA operates as a step-down (buck) converter, efficiently reducing a higher input voltage to a lower output voltage. It utilizes a high-performance controller and power MOSFETs to achieve high efficiency and fast transient response. The converter features a wide input voltage range and a fixed output voltage, providing flexibility and simplicity in various power supply designs.

How Many Pins does LMR33620BDDA have and What are the Functions of the Pinout Configuration?

The LMR33620BDDA is housed in an 8-pin WSON (Wettable Flank SON) package. The pinout configuration includes:

  • VIN: Input voltage pin.
  • SW: Switch node connection for the internal MOSFET.
  • PGND: Power ground connection.
  • AGND: Analog ground connection.
  • SS/TR: Soft-start/tracking input or shutdown pin.
  • FB: Feedback input for output voltage regulation.
  • EN: Enable control input.
  • VOUT: Regulated output voltage pin.

What are the Pros and Cons of LMR33620BDDA?

Pros:

  • Wide Input Voltage Range: Supports a wide input voltage range for versatility in power supply designs.
  • High Efficiency: Provides high efficiency to minimize power loss and reduce thermal stress.
  • Fast Transient Response: Ensures rapid and accurate regulation of the output voltage during load transients.
  • Compact Package: The 8-pin WSON package offers a small footprint for space-constrained applications.
  • Simple Design: Fixed output voltage and integrated features simplify the design and layout of power supplies.

Cons:

  • External Components: May require external components such as input/output capacitors and inductors for proper operation.
  • Heat Dissipation: High efficiency may still require heat sinking in certain high-power applications.
  • Complexity for Beginners: The use of step-down converters may require some understanding of power electronics principles for optimal use.

Are There Any Equivalents/Alternatives to LMR33620BDDA for Recommendation?

  • The LM2675 from Texas Instruments is a similar step-down converter with a different set of features.
  • Alternatives to the LMR33620BDDA include the TPS62160 from Texas Instruments and the LT8610 from Analog Devices.
