TPS61041DRVR in TI TPS6xxxx Bucks & Boosts Family
The TPS61041DRVR is a member of Texas Instruments' high-frequency boost converter family designed to generate output voltages up to 28V from low-voltage supply rails. Operating from an input range of 1.8V to 6V, this DC-DC regulator utilizes a constant-off-time control scheme to minimize power consumption and external component sizes. It is primarily used to provide biasing for LCD displays and white LEDs in battery-operated systems where compact footprint and high efficiency are critical design constraints.
Variants in This Sub-Family
Variants within the TPS6104x sub-family primarily differ by their internal switch current limits and integrated features. While the TPS61041 is limited to 250mA to optimize efficiency for light loads, the TPS61040 offers a higher 400mA limit for increased power delivery. Other variants include specific feedback pin adjustments or specialized internal compensation to accommodate different types of LED strings or LCD bias requirements across various thermal environments.
