FAQs

What is TPS61040DBV?

The TPS61040DBV is a high-efficiency, low-power boost converter IC (integrated circuit) designed by Texas Instruments. It is ideal for applications requiring a regulated output voltage from a single-cell Li-ion battery or similar power sources, such as portable devices, handheld instruments, and wireless sensors.

How Does TPS61040DBV Work?

The TPS61040DBV operates as a boost converter, providing a regulated output voltage that is higher than the input voltage. It uses a switching topology to efficiently step up the input voltage to the desired output level. The IC features a low quiescent current and a wide input voltage range, making it suitable for battery-operated applications.

How Many Pins does TPS61040DBV have and What are the Functions of the Pinout Configuration?

The TPS61040DBV is housed in a 5-pin SOT-23 (Small Outline Transistor) package. The pinout configuration includes:

  • VIN: Input voltage pin.
  • PG: Power good output pin.
  • SW: Switch node for the internal MOSFET switch.
  • GND: Ground connection.
  • VOUT: Regulated output voltage pin.

What are the Pros and Cons of TPS61040DBV?

Pros:

  • High Efficiency: Provides high efficiency for extended battery life in portable devices.
  • Low Quiescent Current: Minimizes power consumption during standby or light load conditions.
  • Wide Input Voltage Range: Accommodates variations in input voltage from the power source.
  • Small Package: The SOT-23 package offers a compact footprint for space-constrained designs.
  • Power Good Output: Provides a signal indicating the output voltage is in regulation.

Cons:

  • Fixed Output Voltage: The output voltage may be fixed, limiting flexibility in certain applications.
  • External Components: May require external components such as inductors and capacitors for proper operation.

Are There Any Equivalents/Alternatives to TPS61040DBV for Recommendation?

  • The TPS61200 from Texas Instruments is a similar boost converter with additional features such as adjustable output voltage.
  • Alternatives to the TPS61040DBV include the LT1301 from Analog Devices and the MCP1623 from Microchip Technology.
