詳細說明

The LMR14006YDDCT is a versatile DC/DC buck regulator designed to handle a wide input range of 4 V-40 V, making it ideal for various applications ranging from industrial to automotive settings. Its ultra-low standby current of 28 µA in sleep mode ensures efficient operation in battery-operated systems, while a shutdown mode with a mere 1 µA current consumption helps prolong battery life. The regulator operates at a fixed frequency of 1.1 MHz (X version) or 2.1 MHz (Y version), enabling the use of compact external components while maintaining low output ripple voltage. With internal soft-start and compensation circuits, the LMR14006 minimizes the need for additional external components. Offering protection features like pulse-by-pulse current limit and thermal sensing, this regulator ensures reliable performance even under high power dissipation conditions. Housed in a low-profile TSOT-6L package, the LMR14006 is a compact and efficient solution for power conditioning needs

主要特徵

常見問題解答

What is LMR14006YDDCT?

The LMR14006YDDCT is a synchronous step-down DC-DC converter designed by Texas Instruments. It is part of the SIMPLE SWITCHER® family and is optimized for high efficiency, small size, and low quiescent current, making it ideal for a wide range of applications including industrial, automotive, and consumer electronics.

How Does LMR14006YDDCT Work?

The LMR14006YDDCT operates as a synchronous buck regulator, converting a higher input voltage to a lower output voltage with high efficiency. It employs a pulse-width modulation (PWM) control scheme to regulate the output voltage and current. The converter features integrated power MOSFETs for reduced external component count and ease of use.

How Many Pins does LMR14006YDDCT have and What are the Functions of the Pinout Configuration?

The LMR14006YDDCT is housed in a 10-pin WSON (Thin Very Small Outline No-Lead) package. The pinout configuration includes:

  • VIN: Input voltage pin.
  • SW: Switch node for the internal power MOSFETs.
  • PGND: Power ground pin for the internal power MOSFETs.
  • FB: Feedback pin for output voltage regulation.
  • EN: Enable pin for turning the converter on and off.
  • SS/TR: Soft-start/tracking pin for controlling start-up behavior.
  • PWM: Pulse width modulation pin for external frequency synchronization.
  • COMP: Compensation pin for loop stability.

What are the Pros and Cons of LMR14006YDDCT?

Pros:

  • High Efficiency: Offers high efficiency conversion for power-sensitive applications.
  • Small Size: Compact WSON package for space-constrained designs.
  • Low Quiescent Current: Helps conserve power during standby or light load conditions.
  • Integrated MOSFETs: Simplifies design and saves board space with integrated power switches.
  • Wide Input Voltage Range: Suitable for various input voltage levels in different applications.

Cons:

  • Complexity: Requires proper layout and external components for optimal performance.
  • Thermal Management: May require heat sinking in high-power applications.
  • Cost: Higher efficiency converters like the LMR14006YDDCT may have a higher price point.

Are There Any Equivalents/Alternatives to LMR14006YDDCT for Recommendation?

  • The TPS62125 from Texas Instruments is a comparable synchronous buck converter with similar features.
  • Alternative options to the LMR14006YDDCT include the LT1763 from Analog Devices and the LM5576 from Texas Instruments.
