APW7060  
Dual Controllers - Step Down Synchronous PWM and Linear Controller  
Features  
General Description  
The APW7060 integrates a synchronous buck PWM  
controller and a linear controller to provide two regu-  
lated voltages in a single package. The PWM control-  
ler drives external N-channel MOSFETs and operates  
at a fixed 600kHz frequency. When the input supply  
drops close to the output, the upper MOSFET remains  
on, achieving 100% duty cycle. Internal loop compen-  
sation is optimized for fast transient response, elimi-  
nating external compensation network. The linear con-  
troller drives an external N-channel MOSFET to form a  
linear regulator. The internal 0.8V reference makes this  
part suitable for a wide variety of low voltage  
applications.  
Provides Two Regulated Voltages  
- One Synchronous DC/DC Buck Controller  
- One Linear Controller  
0.8V Internal Reference Voltage  
- Both Controllers: 0.8V ± 2% Line, Load  
and Temp.  
Output Voltage Range  
- PWM Controller : 0.8V to VIN  
- Linear Controller : 0.8V to (12VCC-VGSpass  
Full Duty Cycle Range for PWM Controller  
- 0% to 100%  
)
The APW7060 has an undervoltage lockout circuitry  
to ensures that both the 5VCC and 12VCC must be  
present before its internal circuitry is power up. Soft  
start is internally set to 2ms and will bring both out-  
puts into regulation in a controlled manner. When ei-  
ther output goes into short, soft start will be initiated.  
If the short condition still remains after three cycles,  
both regulators will be shut down. To restart both  
regulators, recycle the voltage at 5VCC or 12VCC pin  
or momentarily pull the FB2 pin above 1.28V.  
The APW7060 can be shutdown by pulling the FB2  
pin above 1.28V. In shutdown, all gate drive signals  
will be low. This dual controller is available in SO-14  
package.
