The TLV62090RGTT is a buck switching regulator IC positive adjustable 0.8V 1 output, 3A, 16-VFQFN exposed pad manufactured by Texas Instruments. This device is an integrated high-efficiency step-down switching regulator designed to reduce system power consumption and extend battery life, providing high-performance, low-profile power solutions for space-constrained applications. It operates from a 4.5 V to 16 V input supply range and provides excellent line and load regulation over a 0.8 V to 16 V output range. The TLV62090RGTT features fast transient response, low quiescent current, and a wide switching frequency range for optimum efficiency at low output currents. It also includes current and thermal protection including undervoltage lockout, input/output current sensing, power-saving shutdown, cycle-by-cycle current limiting, output short-circuit protection, and thermal shutdown. This device is available in a 16-VFQFN exposed pad package.
