The Texas Instruments TPS51221RTVT is a synchronous, dual-output, peak current mode buck controller designed for notebook system power. It features a wide input voltage range of 4.5V to 28V and can provide output voltages from 1V to 12V.
This controller utilizes a fixed frequency PWM current mode architecture with a selectable light load operation mode. Key electrical specifications include a maximum duty cycle of 99% and a typical quiescent current of 0.0013A. It supports multiple features such as frequency synchronization, phase interleaving, and power good output for each channel.
The TPS51221RTVT is housed in a 32-WQFN (5x5) package and is designed for surface mount applications. Its operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions. The device offers protections including OCL/OVP/UVP/UVLO and thermal shutdown.
Applications for this part include notebook computer systems, I/O bus power, and point-of-load applications in LCD TVs and MFPs.
