The TPS51221RTVR from Texas Instruments is a synchronous, dual-output, peak current mode buck controller. It is designed for notebook computer system power and point-of-load applications in LCD TVs and MFPs. The device supports a wide input voltage range from 4.5V to 28V, with selectable output voltages ranging from 1V to 12V.
Key electrical characteristics include a maximum output current of 20A, a fixed switching frequency between 200kHz and 1MHz, and a maximum duty cycle of 99%. It features current mode control, enabling features such as frequency synchronization, light-load efficiency, phase interleaving, and power good outputs for each channel. The quiescent current is typically 0.0013A.
This controller is housed in a 32-WQFN (5x5 mm) package and supports surface mount installation. It offers multiple selectable light load operations including continuous, auto skip, and out-of-audio skip modes. The TPS51221RTVR also includes programmable droop compensation, voltage servo, adjustable soft start, and integrated bootstrap MOSFET switch. Protection features include OCL/OVP/UVP/UVLO protections and thermal shutdown.
