TPS61040 Description

Short technical summary and product information.

The TPS61040 from Texas Instruments is a high-frequency boost converter ideal for small to medium LCD bias and white LED backlight supplies. It can generate output voltages up to 28V from a single-cell Li-Ion or dual-cell NiMH/NiCd battery, and is also suitable for standard 3.3V or 5V to 12V power conversions.

 

This device features an internal switch current limit of 400mA and operates at a switching frequency up to 1MHz. This high frequency allows for the use of small external components, contributing to a compact overall solution size, especially when paired with the thin WSON package. The TPS61040 boasts a low quiescent current of 28μA typical under no-load conditions and a shutdown current of 1μA typical.

 

Available in SOT-23-5 and WSON packages, the TPS61040 is designed for surface mount applications. Its adjustable output voltage capability and efficient operation make it a versatile choice for portable electronics and display backlighting.

 

Key electrical characteristics include an input voltage range of 1.8V to 6V and an adjustable output voltage range up to 28V. The typical switch current limit is 400mA, with a maximum switching frequency of 1MHz. The device also offers a typical no-load quiescent current of 28μA and a typical shutdown current of 1μA.
