RT8121 - Richtek

RT8121 Single Phase PWM Controller

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.

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 erroramp 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. Features z Single Phase Power Conversion z One Embedded MOSFET Driver with Internal Bootstrap Diode.
