The TPS65261-1RHBR from Texas Instruments is a voltage regulator - switching regulator with 4.5-18V input Vout current triple sync. It is designed for the automatic conversion of input voltages to the required output voltage, and comprises of a voltage reference, oscillator, PWM controller, two-stage amplifier, and a phase switch. This regulator has a maximum output current of 3A and is adjustable to 40 V output voltage. It also includes a frequency synchronization pin, enabling frequency programming from 500kHz to 2.4MHz. This regulator includes a variety of protections, such as over-current, over-temperature, and short-circuit protection. Additionally, it has an adjustable soft start feature, which mitigates inrush current. The TPS65261-1RHBR from TI is a compact, low-profile solution for regulating high-output currents.
