RT8113
Single Phase VR11.1 PWM Controller with 7-bit VID
General Description
The RT8113 is a single-phase PWM buck controller with
one integrated MOSFET driver for advanced
microprocessor applications such as Atom V_CORE or
Ibexpeak Graphic Power. This controller maintains the same
features as the multi-phase product family. However, it
reduces the output to one phase for lower current systems.
Features of this controller include adjustable operation
frequency, power good indication, external error amplifer
compensation, over voltage protection, over current
protection, droop enable/disable capability, externally
adjustable offset voltage, load transient enhancement
(quick response), and enable/shutdown pin to achieve
optimal power management solution for various
applications. The RT8113 comes in a WQFN-24L 4x4
package.
