Synchronous PWM Controller
The NCP3020 is a PWM device designed to operate from a wide
input range and is capable of producing an output voltage as low as
0.6 V. The NCP3020 provides integrated gate drivers and an internally
set 300 kHz (NCP3020A) or 600 kHz (NCP3020B) oscillator. The
NCP3020 also has an externally compensated transconductance error
amplifier with an internally fixed soft−start. Protection features
include lossless current limit and short circuit protection, output
overvoltage protection, output undervoltage protection, and input
undervoltage lockout. The NCP3020 is currently available in a
SOIC−8 package.
