WQFN-24L 4x4

General Description

The RT8113 is a single-phase PWM buck controller with

one integrated MOSFET driver for advanced

microprocessor applications such as Atom VCORE or

IbexpeakGraphic 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.

Features

Single-Phase Power Conversion

One Embedded MOSFET Driver with Internal

Bootstrap Diode
