NCP3012  
Synchronous PWM Controller  
The NCP3012 is a PWM device designed to operate from a wide  
input range and is capable of producing an output voltage as low as  
0.8 V. The NCP3012 provides integrated gate drivers and an internally  
set 75 kHz oscillator. The NCP3012 has an externally compensated  
transconductance error amplifier with an internally fixed softstart.  
The NCP3012 incorporates output voltage monitoring with a Power  
Good pin to indicate that the system is in regulation. The dual function  
SYNC pin synchronizes the device to a higher frequency (Slave  
Mode) or outputs a 180° outofphase clock signal to drive another  
NCP3012 (Master Mode). Protection features include lossless current  
limit and short circuit protection, output overvoltage and undervoltage  
protection, and input undervoltage lockout. The NCP3012 is available  
in a 14pin TSSOP package.
