The Texas Instruments TPS541620RPBR is a versatile DC DC switching regulator designed for step-down applications. It features a wide input voltage range of 4.5V to 15V and supports dual outputs of up to 6A each, or a single output of up to 12A in a dual-phase configuration.
This device utilizes an advanced current mode (ACM/AECM) control for stable operation and offers selectable switching frequencies of 500kHz, 1MHz, 1.5MHz, and 2MHz. The TPS541620RPBR includes integrated 24mΩ and 10mΩ MOSFETs with lossless current sensing. It also provides features such as adjustable current limit, enable, frequency synchronization, power good, prebias startup, and adjustable soft-start.
The regulator is housed in a compact 3mm x 5mm, 25-pin VQFN-HR package, suitable for surface mount applications. Its operating junction temperature range is -40°C to 150°C, ensuring reliable performance in demanding environments. The device supports true differential remote sensing in multi-phase operation and offers independent enable and power good signals for system control.
Key electrical characteristics include an adjustable output voltage from 0.5V to 5.5V and a maximum duty cycle of 92.5%. The fixed soft-start time for dual-output configurations is 1ms. This component is designed for power management solutions requiring high efficiency and precise voltage regulation.
