Preliminary

RT8805C

Two Phase General Purpose PWM Controller

General Description

Features

^z12V Power Supply Voltage

The RT8805C is the most compact dual-phase

synchronous buck controller in the industry specifically

designed for high power density applications. This part is

capable of delivering up to 60A output current due to its

embedded bootstrapped drivers that support 12V + 12V

driving capability.

^z2 Phase Power Conversion

^zEmbedded 12V Boot Strapped Driver

^zPrecise Core Voltage Regulation

^zLow Side MOSFET R_DS(ON)Current Sensing for

Power Stage Current Balance

^zExternal Compensation

The phase currents are sensed by innovative time sharing

^zAdjustable Soft-Start

R_DS(ON)current sensing technique for current balance and

^zAdjustable Frequency and Typical at 300kHz Per

Phase

over current balance. Using one commonGM amplifier to

sense two phase currents eliminates offset and

nonlinearity of the GM amplifier and yields good current

balance. Other features include adjustable operation

frequency from 50kHz to 1MHz, adjustable soft-start,

PGOOD, external compensation, enable/shutdown for

various application and performance consideration.

^zPower Good Indication

^zAdjustable Over Current Protection

z External Reference Voltage Tracking (RT8805CxQVA)

z Small 16-Lead and 24-Lead VQFN Packages

z RoHS Compliant and 100% Lead (Pb)-Free

The RT8805C comes to a tiny footprint package of

VQFN-16L 3x3 and VQFN-24L 4x4 packages.

Applications

z Middle-High EndGPU Core Power

z High End Desktop PC Memory Core Power

z Low Output Voltage, High PowerDensityDC-DC

Converters
