APU3039  
SYNCHRONOUS PWM CONTROLLER  
WITH OVER CURRENT PROTECTION  
FEATURES  
DESCRIPTION  
Current Limit using Lower MOSFET Sensing  
The APU3039 controller IC is designed to provide a syn-  
Using the 6V internal regulator for charge pump  
circuit allows single supply operation up to 18V  
chronous Buck regulator and is targeted for applications  
where the cost and size is critical. The APU3039 oper-  
Programmable Switching Frequency up to 400KHz ates with a single input supply up to 18V. The output  
Soft-Start Function  
voltage can be programmed as low as 0.8V for low volt-  
age applications. Selectable current limit is provided to  
tailor to external MOSFET’s on-resistance for optimum  
cost and performance. The APU3039 features an uncom-  
mitted error amplifier for tracking output voltage and is  
capable of sourcing or sinking current for applications  
such as DDR bus termination.

APPLICATIONS  
DDR Memory VDDQ/VTT Applications  
Graphic Card  
This device features a programmable switching frequency  
set from 200KHz to 400KHz, under-voltage lockout for  
both Vcc and Vc supplies, an external programmable  
soft-start function as well as output under-voltage detec-  
tion that latches off the device when an output short is  
detected.
