TPS51123A Dual-Synchronous Step-Down Controllers

Texas Instruments TPS51123A Dual-Synchronous Step-Down Controllers are wide-input voltage devices targeted for notebook system power supply solutions. The TI TPS1123A supports high-efficiency, fast-transient responses, and provides a combined power-good signal. Out-of-Audio™ mode light-load operation enables low acoustic noise at a much higher efficiency than conventional forced PWM operation. Texas Instruments TPS51123A step-down controllers operate with supply input voltages ranging from 5.5V to 28V and support output voltages from 2V to 5.5V.
