AIC1341  
High Performance, Triple-Output, Auto-  
Tracking Combo Controller  
FEATURES  
GENERAL DESCRIPTION  
n
n
l Provide Triple Accurate Regulated Voltages  
l Optimized Voltage-Mode PWM Control  
l Dual N-Channel MOSFET Synchronous Drivers  
l Fast Transient Response  
The AIC1341 combines a synchronous voltage  
mode PWM controller with two linear controllers  
as well as the monitoring and protection functions  
in this chip. The PWM controller regulates the  
output voltage with a synchronous rectified step-  
down converter. The built-in N-Channel MOSFET  
drivers also help to simplify the design of step-  
down converter. It is able to power CPUs, GPUs,  
memories, chipsets and multi-voltage applications.  
The PWM controller features over current protec-  
tion using RDS(ON). It improves efficiency and saves  
cost, as there is no expensive current sense resis-  
tor required.  
l Adjustable Over Current Protection using RDS(ON)  
.
No External Current Sense Resistor Required.  
l Programmable Softstart Function  
l 200KHz Free-Running Oscillator  
l Robust Outputs Auto-Tracking Characteristics  
l Sink and Source Capabilities with External Circuit  
APPLICATIONS  
l Advanced PC Mboards  
n
Two built-in adjustable linear controllers drive an  
external MOSFETs to form two linear regulators  
that regulates power for multiple system I/O. Out-  
put voltage of both linear regulators can also be  
adjusted by means of the external resistor divider.  
Both linear regulators feature current limit. For a  
system I/O requires current less than 500mA, the  
AIC1340 is recommended for saving one external  
MOSFET.  
l Information PCs  
l Servers and Workstations  
l Internet Appliances  
l PC Add-On Cards  
l DDR Termination  
The programmable soft-start design provodes a  
controlled output voltage rise, which limits the cur-  
rent rate during power on time.  
The shutdown function is also provided for dis-  
abling the combo controller.
