FAQs

What is TPS40200D?

The TPS40200D is a wide input voltage (4.5 V to 52 V), synchronous step-down controller designed by Texas Instruments. It is ideal for applications requiring high-efficiency power conversion, such as industrial, automotive, and telecommunications systems.

How Does TPS40200D Work?

The TPS40200D operates as a synchronous buck converter, regulating the output voltage from a higher input voltage with high efficiency. It utilizes a pulse-width modulation (PWM) control scheme to provide precise regulation of the output voltage. The controller features adjustable soft-start and cycle-by-cycle current limit for reliable and controlled power delivery.

How Many Pins does TPS40200D have and What are the Functions of the Pinout Configuration?

The TPS40200D is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • VCC: Controller supply voltage pin.
  • RT/CLK: Oscillator timing resistor/external synchronization pin.
  • PGND: Power ground pin.
  • COMP: Voltage loop compensation pin.
  • SS/TR: Soft-start/tracking pin.
  • FB: Feedback voltage input pin.
  • FSYNC/SPH: External synchronization pin/power good indicator.
  • INA: Current sense negative input pin.
  • INB: Current sense positive input pin.
  • DRVH: High-side driver output pin.
  • DRVL: Low-side driver output pin.
  • AGND: Analog ground pin.
  • UVLO: Undervoltage lockout pin.
  • SS/TR2: Soft-start/tracking pin.

What are the Pros and Cons of TPS40200D?

Pros:

  • Wide Input Voltage Range: Supports a wide range of input voltages, making it adaptable to various power supply configurations.
  • High Efficiency: Provides high-efficiency power conversion for improved energy conservation.
  • Precise Regulation: Utilizes PWM control for accurate and stable output voltage regulation.
  • Synchronous Operation: Features synchronous rectification for enhanced efficiency and reduced power loss.
  • Adjustable Features: Includes adjustable soft-start and cycle-by-cycle current limit for controlled power delivery.

Cons:

  • External Components: May require additional external components such as inductors, capacitors, and resistors for complete converter implementation.
  • Complexity: Synchronous buck converters may have a more complex design compared to non-synchronous alternatives.
  • Thermal Considerations: Proper thermal management may be required for high-power applications to prevent overheating.

Are There Any Equivalents/Alternatives to TPS40200D for Recommendation?

  • The TPS40057 from Texas Instruments is a comparable wide-input synchronous buck controller with slightly different features.
  • Alternatives to the TPS40200D include the LM5117 from Texas Instruments and the LT3757 from Analog Devices.
