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…
