FAQs

What is TPS61194PWPR?

The TPS61194PWPR is a high efficiency synchronous boost converter designed by Texas Instruments. It is specifically designed for small to medium-sized LCD backlighting applications, making it suitable for portable devices, handheld instruments, and automotive displays.

How Does TPS61194PWPR Work?

The TPS61194PWPR operates as a boost converter, converting a low input voltage to a higher output voltage with high efficiency. It utilizes synchronous rectification to minimize power losses and improve overall efficiency. The converter features adjustable output voltage, current limit protection, and various control features for optimal backlighting performance.

How Many Pins does TPS61194PWPR have and What are the Functions of the Pinout Configuration?

The TPS61194PWPR is housed in a 20-pin HTSSOP (PowerPAD thermally enhanced thin shrink small outline package) package. The pinout configuration includes:

  • VIN: Input voltage pin.
  • VOUT: Output voltage pin.
  • EN (Enable): Enable pin for turning the converter on or off.
  • PWM: Pulse Width Modulation pin for controlling the converter's output voltage.
  • FB (Feedback): Feedback pin for setting the output voltage regulation.
  • PGND, AGND: Power and analog ground pins, respectively.
  • SW: Switch node pin for connecting the inductor and synchronous switch.

What are the Pros and Cons of TPS61194PWPR?

Pros:

  • High Efficiency: Operates with high efficiency to conserve power and extend battery life.
  • Adjustable Output Voltage: Provides flexibility in setting the output voltage for various LCD backlighting requirements.
  • Current Limit Protection: Includes built-in current limiting to protect the converter and load from overcurrent conditions.
  • Compact Package: The HTSSOP package offers a compact footprint suitable for space-constrained applications.
  • Thermal Performance: The PowerPAD package enhances thermal dissipation for improved reliability.

Cons:

  • Complex Design: Requires careful consideration of input voltage, output voltage, and component selection for optimal performance.
  • External Components: May need external capacitors, inductors, and resistors for proper operation.
  • Application Specific: Primarily designed for LCD backlighting applications, may not be suitable for other power supply needs.

Are There Any Equivalents/Alternatives to TPS61194PWPR for Recommendation?

  • The TPS61176 from Texas Instruments offers similar functionality for LCD backlighting applications.
