The NCP3011 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 NCP3011 provides integrated gate drivers and an internally
set 400 kHz oscillator. The NCP3011 has an externally compensated
transconductance error amplifier with an internally fixed soft−start.
The NCP3011 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° out−of−phase clock signal to drive another
NCP3011 (Master Mode). Protection features include lossless current
limit and short circuit protection, output overvoltage and undervoltage
protection, and input undervoltage lockout. The NCP3011 is available
in a 14−pin TSSOP package.
