AP2006  
200KHz, PWM Buck DC/DC & Linear Controller  
„ Features  
„ General Descriptions  
- Provides two regulated voltages  
The AP2006 series are monolithic IC’s containing a  
PWM and a linear power controller. The PWM  
driving a external PMOS. Due to the reduction of  
the number of external components, board space  
can be saved easily. The external shutdown  
function can be controlled by logic level. It switchs  
the IC into the standby mode. The internal  
compensation provides a good line and load  
regulation without external component. Short circuit  
protection prohibits the over current in the output  
switchs. The AP2006 series operate at the  
switching frequency of 250KHz. Therefore, it is able  
to use the smaller sized filters than what used to be  
used with the lower frequency switching regulators.  
Other features include a guaranteed +3% tolerance  
on output voltage under specified input voltage and  
output load conditions, and +20% on the oscillator  
frequency. The linear controller is able to drive an  
external NPN transistor, with 30mA current limit  
pre-driver. The ICs are available in a standard  
SOP8/DIP8 package.  
-one PWM Controller( Drive PMOS)  
-one Linear Controller (Drive NPN and NMOS)  
- Adjustable version: 1.23+/- 2.5%.  
- 250KHz +10% fixed switching frequency  
- Thermal-shutdown and current-limit protection  
- SS/EN Soft-Start/Enable Function.  
- Operating voltage can be up to 22V  
- Low power standby mode  
- Pb-Free Package: SOP8,DIP8  
„ Applications  
- Simple High-efficiency step-down regulator  
- On-card switching regulators  
- XDSL…
