RT8121 is a single phase PWM buck controller with one integrated MOSFET driver for advanced microprocessor application as VR12 VCCIO power. This controller maintains the same features as the multi-phase product family, but reduces the output to one phase for lower current systems. Features of this controller include adjustable operation frequency, power good indication, external error-amp compensation, over voltage protection, over current protection, externally adjustable offset voltage, load transient enhancement (quick response), and enable/shutdown control to achieve optimal power management solution for various applications. The RT8121 comes in the WQFN-20L 3x3 package.
