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?
