Preliminary

RT8805

Two Phase General Purpose PWM Controller

General Description

Features

^z12V Power Supply Voltage

The RT8805 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 Small 16-Lead VQFN Package

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

Applications

The RT8805 comes to a tiny footprint package of

VQFN-16L 3x3 package that is capable of dissipating up

to 1.47W heat.
