TPS61041DBVR Description

Short technical summary and product information.

The TPS61041DBVR from Texas Instruments is a high-frequency boost converter suitable for small to medium LCD bias and white LED backlight supplies. It is designed to generate output voltages up to 28V from a single-cell Li-Ion battery or dual-cell NiMH/NiCd battery.

This device operates with a switching frequency up to 1MHz, enabling the use of small external components. It features an internal switch current limit of 250mA, contributing to lower output voltage ripple. The TPS61041DBVR boasts a low quiescent current of 28uA and a shutdown current of 1uA, optimizing efficiency across various load conditions.

Available in a compact SOT-23-5 package, this boost converter is ideal for applications requiring a small overall design size. It supports PWM dimming for precise brightness control. The operating temperature range is -40°C to 85°C.

Key electrical characteristics include an input voltage range starting at 1.8V, an adjustable output voltage up to 28V, and a switching frequency of 1MHz. The internal switch current is rated at 250mA.
