The TPS65261-1RHBR is an integrated circuit (IC) component designed by Texas Instruments. It is a voltage management device with multiple features aimed at efficient power management.
One of its key features is its ability to provide 3 voltage rails in a single chip. It includes a step-down converter that can generate an output voltage ranging from 0.7V to 3.6V, making it suitable for a variety of applications. Furthermore, it also integrates two low dropout (LDO) voltage regulators, each capable of supplying different output voltages ranging from 0.6V to 3.6V. This allows the TPS65261-1RHBR to provide power for different components with distinct voltage requirements, reducing the need for additional voltage regulators.
An important aspect of the TPS65261-1RHBR is its efficiency. The step-down converter employs a high-performance, step-down architecture with a pulse width modulation (PWM) control. This ensures efficient power conversion, minimizing energy loss and heat generation. The LDO regulators also feature low dropout voltages and low quiescent currents, enhancing overall power efficiency.
Another notable feature is the extensive protection capabilities of the TPS65261-1RHBR. It provides protection against overvoltage, undervoltage, and overcurrent events. Additionally, it includes a thermal shutdown feature to prevent damage due to excessive temperatures
