The TPS51220ARTVT from Texas Instruments is a fixed-frequency, 99% duty cycle, peak current-mode buck controller. It is designed for notebook power systems and point-of-load applications.
This controller features an input voltage range of 4.5V to 32V and an output voltage range of 1V to 12V. It supports D-CAP and current mode control, with selectable light load operation modes including continuous, auto skip, and out-of-audio skip. Key electrical features include a maximum output current of 20A, a typical quiescent current of 0.0013A, and a frequency range of 200kHz to 1MHz.
The TPS51220ARTVT includes several integrated features such as frequency synchronization, phase interleaving, power good output for each channel, and synchronous rectification. It also offers protections for OCL/OVP/UVP/UVLO and non-latch thermal shutdown. The device is available in a 32-WQFN package, specifically the 5x5mm (RTV) or 4x4mm (RSN) variants, with surface mount mounting type.
Applications for the TPS51220ARTVT include notebook computer system and I/O bus power, as well as point-of-load in LCD TVs and MFPs. Its robust feature set and wide operating parameters make it suitable for various power management designs.
